Q.
Two charged particles $M\ and\ N\ $ enter a space of uniform magnetic field, with velocities perpendicular to the magnetic field. The paths are as shown in figure. The possible reason (s) is/are?
A) The charge of $M$ is greater than that of $N$
B) The momentum of $M$ is greater than that of $N$
C) Specific charge of $M$ is greater than that of $N$
D) The speed of $M$ is greater than that of $N$
Explanation
(c) In magnetic field, the radius of circular path
$r = \frac{mv}{Bq} = \frac{v}{B(q/m)}\ ie,\ \ r\ \propto 1/(q/m$)
