The distance moved by a charged particle along the magnetic field (the component of velocity is parallel to the magnetic field) in one rotation is given by (- mass of the particle, 
- velocity of the particle, 
charge of the particle, 
- magnetic field)
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
If the velocity component 
is perpendicular to the magnetic field 
, the magnetic force acts like a centripetal force 
.
and 
Time taken for one revolution
The distance moved by a changed particle along the magnetic field.
