Type: MCQ-conceptual-Medium-Class 12
A particle of mass m, charge Q and kinetic energy T enters a transverse uniform magnetic field of induction 𝐵⃗ . After 3 seconds the kinetic energy of the particle will be
A
4 T
B
3 T
C
2 T
D
T
Correct Answer
Option D
Detailed Explanation
Work done by the magnetic field on a charged particle is zero. Therefore, its kinetic energy will remain the same, i.e., T.
