Q42. a spatially uniform time-dependent magnetic field is changing with time at the constant r 2m rate of 1 t/s. a unit positive charge is moved around a circle

Q42. A spatially uniform time-dependent magnetic field is changing With time at the constant R 2m rate of 1 T/s. A unit positive charge is moved around a circle of radius perpendicular to this field. The magnitude of the work done on the charge for one complete revolution is (a) 0 (b) 2 J (c) 6.28 JJ (d) 12.56J
