A particle of mass m, charge q and kinetic energy T enters in a transverse uniform magnetic field of induction B. After the 3 s, the kinetic energy of the particle will be

A

`2 T`

B

`T`

C

`3 T`

D

`4 T`

Text Solution

Verified by Experts

The correct Answer is:
B

The magnetic field, does not change the energy of the particle. Hence after 3 s, its K.E. will be equal to T.
