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.
Given,
The negative charge alone creates electric field of 30 N/C at point P.
The positive charge has 4x charge as the negative particle.
Distance from P to positive charge is 3x as the distance from P to negative charge.
The direction of electric field due to positive charge is away from it and direction of electric field due to negative charge is towards it.
