An electric

The electric dipole moment can be defined as the measure of the separation of positive as well as negative charges within a specific system. It tells us about the given system’s overall polarity.

Electric dipole moment, p = 4 × 10^–9 C-m

Angle between p and uniform electric field, = 30

Electric field, E = 5 × 10⁴ NC^–1

The torque acting on a dipole is given by:

τ = p × E

τ = p×E×sinθ(θ=30)

= 4 × 10^–9 C m x 5 × 10⁴ NC^–1 x (0.5)

= 10^-4 N m

The magnitude of torque acting on the given dipole is 10^-4 N m.
