Q. The force on a charged particle moving with a velocity $v$ in a magnetic field $B$ is not
A) Perpendicular to both $v$ and $B$
B) Maximum if $v$ is perpendicular to $B$
C) Maximum, if $v$ is parallel to $B$
D) Zero if $v$ is parallel to $B$
Explanation
(c) Force on charged particle
$F = qvB\sin\theta$
Force will be maximum if $\theta = 90{^\circ}$
i.e., if $v$ is perpendicular to $B$
