Question

An electric dipole of moment ´p´ is placed in an electric
field of intensity ´E´. The dipole acquires a position such
that the axis of the dipole makes an angle ϴ with the direction
of the field. Assuming that the potential energy of the dipole
to be zero when = 90°, the torque and the potential energy
of the dipole will respectively be
(a) p E sin ϴ, – p E cos ϴ (b) p E sin ϴ, –2 p E cos ϴ
(c) p E sin ϴ, 2 p E cos ϴ (d) p E cos ϴ, – p E cos ϴ
