In a cylindrical region of radius R there exists a time varying magnetic field B such that dB k 0 A charged particle having charge q is placed at the point P at a distance d R fro dt its centre O Now the particle is moved in the direction perpendicular to OP see figure by an external agent upto infinity so that there is no gain in kinetic energy of the charged particle Choos the correct statement s A Work done by external agent is B Work done by external agent is C Work done by external agent is D Work done by external agent is 97R 4 k if d 2R qaR 8 k if d 4R 97R 4 k if d 4R q R 4 k if d 6R
