Physics · Electrostatics
An electron of mass me, initially at rest, moves through a certain distance in a uniform electric field in time t1. A proton of mass mp, also initially at rest, takes time t2 to move through an equal distance in th is same uniform electric field. Neglecting the effect of gravity, the ratio t2t1 is equal to:
- 1mp / me
- 2(me / mp)1/2
- 3(mp / me)1/2✓
- 41
Correct answer
(mp / me)1/2
