F = 5i + 3j Newtons acts 3 m to the right of the origin (x is horizontal and y is vertical). What moment does this force produce about the origin? Use the vector cross product.

Who says you have only one vector? Remember, a vector has magnitude and direction.

Does this help?

[itex]\bar{M}_{o} = \bar{R}[/itex] X [itex]\bar{F}[/itex]
