Physics Question 35 – NEET-UG 2025

An electric dipole with dipole moment $5\times {10}^{-6}$ Cm is aligned with the direction of a uniform electric field of magnitude $4\times {10}^5$ N/C. The dipole is then rotated through an angle of ${60}^{\circ }$ with respect to the electric field. The change in the potential energy of the dipole is :
