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.

Text Solution
