Find the torque of a force \overrightarrow{F}=-3 {i} ^{\^}+ \stackrel{\^}{j}+5 \stackrel{\^}{k} acting at the point \overrightarrow{r}=7 \stackrel{\^}{i}+3 \stackrel{\^}{j}+ \stackrel{\^}{k} (1997)

Correct Answer is : 14^i−38^j+16^k

-14 \stackrel{\^}{i}+34 \stackrel{\^}{j}-16 \stackrel{\^}{k}

14 \stackrel{\^}{i}-38 \stackrel{\^}{j}+16 \stackrel{\^}{k}

4 \stackrel{\^}{i}+4 \stackrel{\^}{j}+6 \stackrel{\^}{k}
