Question

a particle of mass mand charge q, moving with a velocity v, enters a region of uniform magnetic field B as shown in the figure below. the particle strikes the wall at a distance d rom the entrance slit. If the particle's velocity remains the same but its charge-to-mass ratio is doubled, at what distance (in terms of d) from the entrance slit will the particle strike the wall?

Answer 1

R = mv/qb

R’ = mv/2qb = R/2
