NEETPhysicsElectrostaticsMCQ+4 / −1

An electric dipole with dipole moment 5×10−6Cm5 \times 10^{-6} \mathrm{Cm}5×10−6Cm is aligned with the direction of a uniform electric field of magnitude 4×105 N/C4 \times 10^5 \mathrm{~N} / \mathrm{C}4×105 N/C. The dipole is then rotated through an angle of 60∘60^{\circ}60∘ with respect to the electric field. The change in the potential energy of the dipole is:

  1. A
    1.2 J
  2. B
    1.5 J
  3. C
    0.8 J
  4. D
    1.0 J
