easy

A charged particle is moving with velocity $v$ in a magnetic field of induction $B$. The force on the particle will be maximum when

A

$v$ and $B$ are in the same direction

B

$v$ and $B$ are in opposite directions

C

$v$ and $B$ are perpendicular

D

$v$ and $B$ are at an angle of $45^\circ $

Solution

(c) Lorentz force $F = \left( {v \times B} \right)$ or $\left| F \right| = qvB\sin \theta $ will be maximum. when $\theta = {90^o}$
