. An electron of mass me, initially at rest, moves though a certain distance in a uniform electric field in time t2 A proton of mass mp, aslo, initially at rest, takes time t2­ to move though an equal distance in this uniform electric field. Neglecting the effect of gravity, the ratio t2 / t1 is nearly equal to (a) 1(b) (mp / me)1/2(c) (me / mp)1/2(d) 1836
