An electron moving in a uniform magnetic...

An electron moving in a uniform magnetic field of B has its radius directly proportional to

A

its charge

B

magnetic field

C

speed

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
C
As per relation `r = (mv)/(qB)`, the radius of circular path of electron, when a magnetic field B is applied at right angles to its motion, is directly proportional to its speed i.e., `r prop v`
