Force on a charged particle moving in a magnetic field

Question

A proton and an electron, both moving with the same velocity v, enter into a region of magnetic field directed perpendicular to the velocity of the particles. They will now move in circular orbits such that

Moderate

A

Their time periods will be same
B

The time period for proton will be higher
C

The time period for electron will be higher
D

Their orbital radii will be same

Solution

We know that time period, $T = \frac{2 πm}{qB}, i . e ., T \propto m$
(Since q and B are same)
$∵$ Mass of proton > Mass of electron
$∴$ Time period of proton > Time period of electron
