A force is said to do **work** if, when acting on a body, there is a displacement of the point of application in the direction of the force.

The work done by a constant force of magnitude

So, in this case,

Work done,

I think the weight of the body is perpendicular to the displacement in this case. So, as the force applied along the displacement or at any other angle other than

Plus, the dot product of F and S is

The question would have been clearer if the direction of applied force and its magnitude were given or the direction of displacement was given.
