A sample of HCl g
Electric field : E = 2.5 × 104 N C–1
Dipole moment of each HCl molecule :
P = 3.4 × 10–30 cm = 3.4 × 10–30 Cm .
Torque acting on a dipole is given as
Where, τ is the torque acting on the dipole, P is the dipole moment of the HCl molecules and E is the electric field.
τ = PEsinθ
For maximum torque θ = 90°
Thus sin(90) = 1
Hence a maximum of 8.5× 10-26 Nm of torque can act on a HCl molecule.
