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 0 with the direction of the field. Assuming that the potential energy of the dipole is zero when `0=90^@`, the torque and the potential energy of the dipole will respectively be

A

pEsin`theta`, - pEcos`theta`

B

pEsin`theta`, - 2pEcos`theta`

C
