An electron of mass `m_(e )` initially at rest moves through a certain distance in a uniform electric field in time `t_(1)`. A proton of mass `m_(p)` also initially at rest takes time `t_(2)` to move through an equal distance in this uniform electric field.Neglecting the effect of gravity, the ratio of `t_(2)//t_(1)` is nearly equal to

Options

A. `((m_(p))/(m_(e)))^(1//2)`
B. `((m_(e))/(m_(p)))^(1//2)`
C. 1
D. 1836

Answer

A
