A ring of mass m and radius R is set into pure rolling on horizontal rough surface in a uniform magnetic field of strength B as shown in the figure A point charge q of negligible mass is attached to rolling ring Friction is sufficient so that it does not slip at any point of its motion is measured in clockwise from po de mmmmmm Ring will continue to move with constant velocity The value of friction acting on ring is Bqv cos The value of friction acting on ring is Bqv sin mg 9 P
