Question

The torque of a force $5 \hat{i}+3 \hat{j}-7 \hat{k}$ about the origin is $\tau$. If the force acts on a particle whose position vector is $2 \hat{i}+2 \hat{j}+\hat{k}$ , then the value of $\tau$ will be :

Select the correct option:

A

$11 \hat{i}+19 \hat{j}-4 \hat{k}$

B

$-11 \hat{i}+9 \hat{j}-16 \hat{k}$

C

$-17 \hat{i}+19 \hat{j}-4 \hat{k}$

D

$17 \hat{i}+9 \hat{j}+16 \hat{k}$
