A particle of mass m, charge Q and kinetic enery T enters a transverse uniform magnetic field of induction B⃗. After 3 seconds, the kinetic energy of the particle will be:
Options
(a) 3T
(b) 2T
(c) T
(d) 4T
Correct Answer:
T
Explanation:
When a charged particle enters a transverse magnetic field it traverse a circular path. Its kinetic energy remains constant.
