Q. An electron and a proton with equal momentum enter perpendicularly into a uniform 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
C) Both are equally curved
D) Path of both will be straight line
Explanation
(c) $r = mv/qB$
Since both have same momentum, therefore the circular path of both will have the same radius
