An electric dipole with dipole moment 5 × 10–6 Cm is aligned with the direction of a uniform electric field of magnitude 4 × 105 N/C. The dipole is then rotated through an angle of 60° with respect to the electric field

An electric dipole with dipole moment 5 × 10^–6 Cm is aligned with the direction of a uniform electric field of magnitude 4 × 10^5 N/C. The dipole is then rotated through an angle of 60° with respect to the electric field. The change in the potential energy of the dipole is: 

(1) 0.8 J                    (2) 1.0 J 

(3) 1.2 J                   (4) 1.5 J                      (NEET-2025)
