AIPMT PRELIMS 2008 Physics Motion of Charged Particles MCQ Question
Type: MCQ-conceptual-Easy-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
1 T
B
4 T
C
3 T
D
2 T
Correct Answer
Option A
Detailed Explanation
In a uniform magnetic field, the kinetic energy of a charged particle remains constant as the magnetic force does no work. Hence, the kinetic energy remains T.
