उत्तर

Given:
Electric field intensity, E = 2.5 × 104 NC−1
Dipole moment of an HCl molecule, P = 3.4 × 10−30 Cm
Torque on the molecule, 

\[\Gamma = PE\sin\theta\]

For

\[\Gamma_{max}\] , putting sinθ = 1, we get
\[\Gamma_{max}  = PE\] 

\[               = 3 . 4 \times  {10}^{- 30} 2 . 5 \times  {10}^4 \] 

\[               = 8 . 5 \times  {10}^{- 26} \]  Nm
