Electrostatic Force Essay
1.5 Electrostatic Forces We just studied that like charges repel each other and unlike charges attract each other. These attractive and repulsive forces are called electrostatic forces. Consider a system of two charges q1 and q2 Where q1 = + 5 C and q2 = + 50 C As both the charges are positive, they will repel each other with forces F1 and F2 as shown in the figure below. Can you tell which force is greater, F1 or F2? Magnitude of charge q2 is greater than magnitude of charge q1. But this does not matter here. F1 and F2 are action-reaction pair, so force applied by charge q1 on q2 is equal and opposite to the force applied by q2 on q1. Similarly, if we have two opposite charges say q1 = 5 C and q2 = – 50 C. They will experience equal and opposite attractive forces. …show more content…
According to Coulomb’s law, net force acting on one charge due to another charge can be given as–
Where, k is some constant.
• Formulae says that net force experienced by any charge is directly proportional to product of charges. F q1 q2 If we increase magnitude of charges then force will also increase.
• It also says, net force experienced by any charge is inversely proportional to square of distance between them. As r increases, F will decrease. This looks reasonable. 1.6.1 Features of Coulomb's Law
1. Coulomb’s Law is applicable only for point charges. We cannot use this law to calculate electrostatic force between any two big objects. If an arbitrary shaped body A has charge q1 and another arbitrary shaped body B has charge q2 then forces between these two bodies cannot be given by Coulomb’s law.
2. The proportionality constant k has value: k = 9 × 109 N m2/C2. k can be written as Where, 0 is another constant called permittivity of free space.
3. If we place charges in any medium such as glass or water then value of k can be written

Their results would line up with the following; that if the two pieces of tape are torn from the same 40 centimeter strip then the tops of both pieces of tape would be positive and the bottoms of both pieces of tape would be negative and that if they would double the tape the attraction or repulsion in general would lower due to the increased density. Their data would also show that two pieces of tape ripped from each other would result in one piece being entirely positive and the other being entirely negative, they would also be able to state that the orientation of how the tape is paired up doesn’t matter.

Whereas, if you had a negative charge, it would increase the radius because now there's an extra electron. I noticed that there's a relationship between the first ionization

They share electrons to fill up their outer shells, this makes the atoms stable. A Covalent bond can form up to one to three Covalent bonds with non-metals depending on how much electrons they possess. They don't always share electrons

Resting Membrane Potential Lab Report
1566 Words | 7 PagesRESTING MEMBRANE POTENTIAL When the neuron is not sending a signal at rest the membrane potential called as resting membrane potential. In this stage, permeability of K+ much greater than Na+ When a neuron is at rest, the inside of the neuron is negative relative to the outside. Although the concentrations of the different ions endeavor to balance out on both sides of the membrane, they cannot because the cell membrane sanctions only some ions to pass through channels (ion channels). At rest, potassium ions (K+) can cross through the membrane facilely. Additionally at rest, chloride ions (Cl-) and sodium ions (Na+) have a more arduous time crossing.

1225 Words | 5 PagesActivity 1 Increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels because it caused to decrease in the concentration gradient. Increasing extracellular K+ causes the membrane potential to change to a less negative value because extracellular K+ is increasing, which it will cause intracellular K+ to be less. A change in extracellular Na+ did not alter the membrane potential in the resting neuron because there are a lot of K+ leak channels than Na+ leak channels The relative permeability of the membrane to Na+ and K+ in a resting neuron is that Na+ leak channel is less, but K+ leak channels has more so the membrane become less permeable to Na+.

2031 Words | 9 PagesElectrical charge is static electricity, or electricity that does not move. The knowledge of electricity dates back to 600 B.C. While the Greeks did not know they had discovered static electricity, they observed that rubbing fossilized tree resin, or amber, with animal fur made the resin attract dried grass. In 1600 AD. An English physicist named William Gilbert wrote books on the attractive nature of amber and used the Latin word "electricus" as a description. Several years later, another Englishman was inspired by Gilbert, his name was Thomas Browne.

If an object (Object A) exerts a force onto another object (Object B), Object B will exert the same force back, just in the opposite direction. A finger is exerting a force on to the wall. According to Newton’s Third Law of Motion, the wall should be exerting the same amount of force, just in the opposite direction, to the finger.

These electrolytes are the same ones that replenish your body after exercise. Gatorade and other drinks have different electrolyte activity rates. That makes the battery either more or less powerful. A battery can be made with more electrolyte containing materials than you think.

The conclusion of its motion is the amount of work being done. Kinetic energy can be passed from one object to another by clashing towards each other.
Electrolysis In Chemistry Ia
2800 Words | 12 PagesChemistry IA Background information: Introduction: Electrolysis it’s a chemical process that when you pass an electric current into a solution or a liquid that contains ions to separate substances back to their original form. The main components that are required for electrolysis to take a place are: Electrolyte: it’s a substance that when dissolved in water it ionize and then it will contain free moving ions and without these moving ions the process of electrolysis won’t take place. Direct current (DC): This current provides the energy needed to discharge the ions in the electrolyte Electrodes: it’s an object that conducts electricity and it’s used in electrolysis as a bridge between the solution and power supply. A great example
Hodgkin-Huxley Model Essay
895 Words | 4 PagesSince equilibrium cannot be reached, an electrochemical driving force is generated which acts on the ions. It is derived by finding the difference between the membrane potential obtained and the equilibrium potential expected. The sign of the value of this force decides the direction of movement of ions. Since we have cations (positive ions), a positive value shows movement of ions outside the cell membrane and a negative value shows movement of ions inside the cell membrane. If the value is equal to that of the equilibrium potential, the driving force acting on the ion is 0.
