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

3T

B

2T

C

T

D

4T

Text Solution

Verified by Experts

The correct Answer is:
C

After pasing through a magnetic field, the magnitude of its mass and velocity of the particle remain same, so its energy does not change, ie, kinetic energy will remain T.
