An electric dipole with dipole moment $3 × 10^{-9} Cm$ is aligned at 30° with the direction of uniform electric field of magnitude $6 × 10^4 NC^{-1}$. What will be the magnitude of the torque acting on the dipole?

$9×10^{-5} Nm$ $2.5 × 10^{-14} Nm$ $2×10^{13} Nm$ $1.56 × 10^{-4} Nm$

$9×10^{-5} Nm$

The correct answer is Option (1) → $9×10^{-5} Nm$
