A sample of HCl gas is placed in an electric field of $3 × 10^4 NC^{-1}$. The dipole moment of each HCl molecule is $6× 10^{-30} Cm$. The maximum torque that can act on this molecule is:

$2× 10^{-34} C^2 N^{-1} m$ $2×10^{-34} N^{-1} m$ $18×10^{-26} N m$ $0.5×10^{-34} C^2 N^{-1} m^{-1}$

$18×10^{-26} N m$

The correct answer is Option (3) → $18×10^{-26} N m$
