What is the torque of force \(\bar{F}=2 \hat{i}-3 \hat{j}+4 \hat{k}\) acting at a point \(\bar{r}=3 \hat{i}+2 \hat{j}+3 \hat{k}\) about the origin?
- \(6 \hat{i}-6 \hat{j}+12 \hat{k}\)
- \(-6 \hat{i}+6 \hat{j}-12 \hat{k}\)
- \(17 \hat{i}-6 \hat{j}-13 \hat{k}\)
- \(-17 \hat{i}+6 \hat{j}+13 \hat{k}\)
Answer
(C) 17 i -6 j -13 k
