A slab is subjected to two forces F1 and F2 of same magnitude as shown in the figure. Force F2 is in xy-plane while force F1 acts along Z-axis at the point \(\left( {2\hat i + 3\hat j} \right).\) The moment of these forces about point O will be

A. \(\left( {3\hat i + 2\hat j - 3\hat k} \right)F\)
B. \(\left( {3\hat i - 2\hat j + 3\hat k} \right)F\)
C. \(\left( {3\hat i - 2\hat j - 3\hat k} \right)F\)
D. \(\left( {3\hat i + 2\hat j + 3\hat k} \right)F\)
Answer» C. \(\left( {3\hat i - 2\hat j - 3\hat k} \right)F\)
