Q. A particle of mass ‘m’ and carrying a charge ‘q’ enters with a velocity ‘v’ perpendicular to a uniform magnetic field. The time period of rotation of the particle

2801 168 WBJEEWBJEE 2016 Report Error

A

Decreases with increase of velocity v

B

Increases with increase of radius of the orbit

C

Depends only on magnetic field

D

Depends on magnetic field and (q/m) of the particle

Solution:

$(T = \frac{2 πm}{qB})$
