There exists a uniform magnetic field perpendicular to the plane of the figure in a cylindrical region of radius a. The magnetic field is increasing at a constant rate of alpha Ts^(-1) . A particle having charge q is at a point P outside the field region. The particle is slowly moved to infinity. Calculate work done by the external agent on the particle if- (a) the particle is moved in radial direction OP. (b) the particle is moved in a direction perpendicular to OP along PQ.
