A metal sphere of radius b has a uniform surface charge distribution ρs. Consider that the permittivity of the surrounding region is given by E = E0(1+a/r). CALCULATE 1. the energy density 2. expression for the potential V in the dielectric region
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.
