Question

mention an expression for electric potential energy of system of two point charges in the presence of external electric field and explain the symbols​

Answer 1

Answer:

electric potential is defined as the potential energy per unit charge, i.e. V=PEq V = PE q . ... The equation for the electric potential due to a point charge is V=kQr V = kQ r , where k is a constant equal to 9.0×109 N⋅m2/C2.
