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.
I want to know when we calaculate the electric field at the dot in the given figure then why we take difference in voltage as 200-100? Why not 100-0 ? As both the equipotential surfaces are equidistant from each other . Please explain in detail. If possible then also mention some book to understand this in depth.
