A sample of $HCl$ gas is placed in an electric field $3 \times 1 0^{4} NC^{- 1}$ . The dipole moment of each $HCl$ molecule is $6 \times 1 0^{- 30} cm$ . The maximum torque that can act on a molecule is

Answer:

Solution:

Here $E = 3 \times 1 0^{4} NC^{- 1} p = 6 \times 1 0^{- 30} Cm Γ_{m a x} = ?$ We have, torque acting on a dipole $Γ = pE sin θ$ The maximum value of $Γ$ , i.e. $Γ_{m a x} = pE$ $∴ Γ_{m a x} = (3 \times 1 0^{4} \times 6 \times 1 0^{- 30}) Nm = 18 \times 1 0^{- 26} Nm$
