both force and displacement is vector quantity. But when we multiply these both quantites, we get work, which is a scalar quantity. How? (I know work has only magnitude)

Solution

Work is defined as a scalar because it depends on the net distance involved, regardless of the direction. If the object winds up where it started, no work is performed because the distance is zero.
Displacement and force are both vector quantities because they have both magnitude and direction.
