Question
An electron falls from rest through a vertical distance h in a uniform and vertically upward directed electric field E. The direction of electrical field is now reversed, keeping its magnitude the
same. A proton is allowed to fall from rest in through the same vertical distance h. The time fall of the electron, in comparison to the time fall of the proton is :-
Options
A.
smaller
B.
5 times greater
C.
10 times greater
D.
equal
Solution
as mass of proton is heavier than electron, hence electron will take less time.
