Unformatted text preview: continuous lines tangential to the electric field vectors Force on a charge ( ) in an given electric field ( ): For conductors at electrostatic equilibrium: Any excess charge resides on the surface of the conductor The electric field is zero at any point inside a conductor. The conductor shields any charge inside it from electric fields created outside of the conductor. Electric field just outside of the conductor is perpendicular to its surface. + + = 2 1 E E E r r r + 1 E r E r 2 E r 1 q 2 q (Principle of Superposition) Electric Field (Cont) E q F r r = E r q...
