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 to be zero when θ=900, the torque and the potential energy of the dipole will respectively be

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 to be zero when θ=900, the torque and the potential energy of the dipole will respectively be

An electric dipole is placed at an angle of 30o with an electric field intensity 2×105N/C. It experiences a torque equal to 4Nm. The charge on the dipole if the dipole length is 2 cm is
