A particle of mass M and charge Q moving with velocity v describes a circular path of radius R when subjected to a uniform transverse magnetic field of induction B. The work done by the field when the particle completes one full circle is :

A

`BQv^2 2pi R`

B

`((M^2)/R)2piR`

C

Zero

D

`BQ2piR`

Text Solution

Verified by Experts

The correct Answer is:
C
Since, path of charge particle is circular
Hence, W = 0 as `F bot` displacement.
