Question

$\frac{1}{2} (3 \hat{i} - \hat{j} - \hat{k}) m$
$\frac{1}{2} (3 \hat{i} + \hat{j} - \hat{k}) m$
$\frac{1}{2} (3 \hat{i} - \hat{j} + \hat{k}) m$
$\frac{1}{2} (3 \hat{i} + \hat{j} + \hat{k}) m$

The correct answer is: $1 half left parenthesis 3 i with hat on top plus j with hat on top minus k with hat on top right parenthesis m$

$1 half left parenthesis 3 i with hat on top plus j with hat on top minus k with hat on top right parenthesis m$
