The torque of a force 5 i +3 j -7 k about the origin is τ. If the force acts on a particle whose position vector is 2 i +2 j + k, then the value of τ…
The torque of a force $\displaystyle 5 \hat{i}+3 \hat{j}-7 \hat{k}$ about the origin is $\displaystyle \tau$. If the force acts on a particle whose position vector is $\displaystyle 2 \hat{i}+2 \hat{j}+\hat{k}$, then the value of $\displaystyle \tau$ will be
Official answer
(3)
$\displaystyle -17 \hat{i}+19 \hat{j}-4 \hat{k}$
