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
WBJEE
WBJEE 2016
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:
$\left(T=\frac{2\pi m}{qB}\right)$
