Question

A charged particle carrying charge 1 $\mu $C is moving
with velocity $\left( {2\widehat i + 3\widehat j + 4\widehat k} \right)$ ms^–1. If an external
magnetic field of $\left( {5\widehat i + 3\widehat j - 6\widehat k} \right)$× 10^–3 T exists in the region where the particle is moving then the
force on the particle is $\overrightarrow F $ × 10^–9 N. The vector $\overrightarrow F $ is :

${ - 0.30\widehat i + 0.32\widehat j - 0.09\widehat k}$

${ - 300\widehat i + 320\widehat j - 90\widehat k}$

${ - 30\widehat i + 32\widehat j - 9\widehat k}$

${ - 3.0\widehat i + 3.2\widehat j - 0.9\widehat k}$
