Force \(\hat{i}\ +\ 2\hat{j}\ -\ \hat{k}\) and \(\hat{i}\ -\ \hat{j}\ +\ \hat{k}\) are acting on a particle at the point (2, 1, 2). The moment of the forces about the point (1, 2, 1) is
1
\(-\hat{i}\ +\ 2\hat{j}\ -\ 3\hat{k}\)
2
\(-\hat{i}\ -\ 3\hat{j}\ -\ 2\hat{k}\)
3
\(\hat{i}\ -\ 2\hat{j}\ -\ 3\hat{k}\)
4
\(-\hat{i}\ -\ 2\hat{j}\ +\ 3\hat{k}\)
