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.

Question

(d) When a conservative force does negative work, which way do the force and
infinitesimal displacement vectors point relative to one another? When a
conservative force does negative work, what happens to the associated potential
energy function?
(e) What is a capacitor? What does a capacitor do?
