A proton and an electron both moving wi...

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 cirular orbits such that

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

Text Solution

Verified by Experts

The correct Answer is:
B

We know that time period `T=(2pim)/(qB)` i.e. `Tpropm`
(Since `q` and `B` are same )
`:'` Mass of protongtMass of electron
`:.` Time period of protongtTime of electron
