Question

A constant force $stack F with rightwards arrow on top$ = 3 $stack i with hat on top$ + 2 $stack j with hat on top$ – 4 $stack k with hat on top$ is applied at point A (1, –1, 2). Then vector moment of $stack F with rightwards arrow on top$ about point B (2,–1, 3) is -

–2 $\hat{i}$ + 7 $\hat{j}$ + 2 $\hat{k}$
–2 $\hat{i}$ – $\hat{j}$ +2 $\hat{k}$
2 $\hat{i}$ + 7 $\hat{j}$ – 2 $\hat{k}$
None of these

The correct answer is: None of these
