AIPMT PRELIMS 2009 Physics Motion of Charged Particles in Magnetic Field MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Under the influence of a uniform magnetic field, a charged particle moves with constant speed V in a circle of radius R. The time period of rotation of the particle:
A
depends on R and not on V
B
is independent of both V and R
C
depends on both V and R
D
depends on V and not on R
Correct Answer
Option B
Detailed Explanation
The time period T of a charged particle moving in a magnetic field is given by T = 2πm/qB, which is independent of both V and R.
