Question
An electric dipole when held at 30 ֯ with respect to a
uniform electric field of 103 N/c experience a torque of 12 × 10-26 Nm. Calculate dipole moment of the dipole?Solution
Given that: θ = 30֯ τ = 12 × 10-26 Nm E = 103 N/C Dipole moment P needs to be calculated. It is known that torque is given by τ = PE sin θ => P = τ/ E sin θ => P = (12 × 10-26)/( 103 × sin 30 °) = 24 × 10-29 Cm
