Vedclass · Answer

(D) The moment of a force $\overrightarrow{F}$ acting at a point $P$ about a point $C$ is defined as the cross product of the position vector of $P$ relative to $C$ and the force vector $\overrightarrow{F}$.Mathematically,the moment $\overrightarrow{	au}$ is given by $\overrightarrow{	au} = \overrightarrow{r} 	imes \overrightarrow{F}$,where $\overrightarrow{r} = \overrightarrow{CP}$.Therefore,the moment is $\overrightarrow{CP} 	imes \overrightarrow{F}$.

The moment of the force $\overrightarrow{F}$ acting at a point $P$,about the point $C$ is:
