MCQ

If an electron and a proton having same momenta enter perpendicular to a magnetic field, then

A
The path of proton shall be more curved than that of electron
B
The path of proton shall be less curved than that of electron
✓
Both are equally curved
D
Path of both will be straight line

✓

Answer

Correct option: C.

Both are equally curved

c
(c) $r = mv/qB$
Since both have same momentum, therefore the circular path of both will have the same radius.
