Problem

A charged particle carrying charge

1 \mu\text{C}

is moving with velocity

(2\hat{i} + 3\hat{j} + 4\hat{k}) \text{ ms}^{-1}

. If an external magnetic field of

(5\hat{i} + 3\hat{j} - 6\hat{k}) \times 10^{-3} \text{ T}

exists in the region where the particle is moving then the force on the particle is

\vec{F} \times 10^{-9} \text{ N}

. The vector

\vec{F}

is : (1)

-0.30\hat{i} + 0.32\hat{j} - 0.09\hat{k}

(2)

-30\hat{i} + 32\hat{j} - 9\hat{k}

(3)

-300\hat{i} + 320\hat{j} - 90\hat{k}

(4)

-3.0\hat{i} + 3.2\hat{j} - 0.9\hat{k}
