The diagram below shows some equipotential surfaces associated with the assemblage of three field charges. A fourth (test) charge is brought in, with a charge of q = -2.5 nC, and deposited at point A. How much work would it take to relocate this test charge from point A to point B?
Dielectric Constant Of Water
Water constitutes about 70% of earth. Some important distinguishing properties of water are high molar concentration, small dissociation constant and high dielectric constant.
Electrostatic Potential and Capacitance
An electrostatic force is a force caused by stationary electric charges /fields. The electrostatic force is caused by the transfer of electrons in conducting materials. Coulomb’s law determines the amount of force between two stationary, charged particles. The electric force is the force which acts between two stationary charges. It is also called Coulomb force.
