At what angle of electric dipole moment with uniform electric field, potential energy is maximum ?

Electric dipole is placed in external electric field. When the potential energy of dipole is maximum?

A dipole of electric dipole moment p is placed in a uniform electric field of strength E. If theta is the angle between positive direction of p and E, then the potential energy of the electric dipole is largest when theta is
