I Electrostatic Force 1Frictional Electricity2Properties of Electric Charges3Coulomb. In an equilibrium situation there cannot be an electric field inside a conductor as this would cause charges electrons or ions to move around Charge density inside a conductor is zero This follows from Gausss law As the charge density This does no r
