1.	A sample of HCl gas is placed in an electric field of 2.5 × 104 N C−1. The dipole moment of each HCl molecule is 3.4 × 10−30 C m. Find the maximum torque that can act on a molecule.
Answer» E = 2.5 × 10⁴ N C⁻¹ , p = 3.4 × 10⁻³⁰ C m. Torque acting on the molecule τ = pE sin θ for maximum torque, θ = 90° = 3.4 × 10⁻³⁰ × 2.5 × 10⁴ Maximum Torque acting on the molecule is = 8.5 × 10⁻²⁶ N m.

A sample of HCl gas is placed in an electric field of 2.5 × 104 N C−1. The dipole moment of each HCl molecule is 3.4 × 10−30 C m. Find the maximum torque that can act on a molecule.

Answer»

E = 2.5 × 10⁴ N C⁻¹ , p = 3.4 × 10⁻³⁰ C m.

Torque acting on the molecule τ = pE sin θ for maximum torque, θ = 90° = 3.4 × 10⁻³⁰ × 2.5 × 10⁴

Maximum Torque acting on the molecule is = 8.5 × 10⁻²⁶ N m.
