Question

A particle of charge q and mass m is moving with a velocity - v i ^ ( v ≠ 0 ) towards a large screen placed in the Y - Z plane at distance d. If there is magnetic field B → = B 0 k ^ , the minimum value of v for which the particle will not hit the screen is :, qdB 0 3 m, 2 q d B 0 m, q d B 0 m, qdB 0 2 m

The radius of circular path in given magnetic field is r = d = m v q B 0 so v = q B 0 d m
