Question
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 this uniform electric field. Neglecting the effect of gravity, the ratio, t2/t1 is nearly equal to:
Options
A.1
B.(mp/me)1/2
C.(me/mp)1/2
D.1836
Solution
t = 
∴ t ∝
∝ √m
[when x, q & E are same]
∴ t ∝ ∝ √m[when x, q & E are same]
