A particle mass `m` charge `Q` and kinetic energy `T` eneters transverse unifrom magnetic fiedl of induction `vec(B)` After `s` the kinetic energy or the particle will be

A

`3T`

B

`2T`

C

`T`

D

`4T`

Text Solution

Verified by Experts

The correct Answer is:
C
After passing through a magnetic field, the magntitude of its mass and velocity of the particle remain the same, so its energy does not charge, i.e., kinetic energy will remain `T`.
