Question

electric potential energy possessed by a charge Q is placed at the equatorial position of an electric dipole (p =2qa) at a distance r from the centre of the dipole is​

Answer 1

The potential energy of the dipole is zero, when the angle between dipole moment →p and electric field →E is π2. Also, the potential energy of the dipole moment is maximum, that is +pE when the angle between dipole moment →p and electric field →E, is π.
