Q.

A slab is subjected to two forces $F_{1}$ and $F_{2}$ of same magnitude F as shown in the figure. Force $F_{2}$ is in XY-plane while force $F_{1}$ acts along z-axis at the point $(2 i + 3 j)$ The moment of these forces about point O will be.

A
$(3 \hat{i} - 2 \hat{j} + 3 \hat{k}) F$
B
$(3 \hat{i} + 2 \hat{j} - 3 \hat{k}) F$
C
$(3 \hat{i} + 2 \hat{j} + 3 \hat{k}) F$
D
$(3 \hat{i} - 2 \hat{j} - 3 \hat{k}) F$
