A uniformly charged solid sphere with a radius of 0.6 m and net electric charge of 450 nC is rotating with angular speed of 3 rad/s. The axis of rotation is indicated by the dashed line. The magnitude of the constant external magnetic field has a magnitude of 7 mT. What is the magnitude of dipole contribution to the net torque (in pNm) exerted on the sphere due to its interaction with the external magnetic field if θ = 60∘?
