The work done on the object by the force of gravity is zero joules.
Explanation:
Gravity is vertically downwards, and the object moves horizontally. The work done in the integral of Force dot product with dr where dr is the vector displacement infinitesimal. Since the force of gravity is vertical, and dr is horizontal, they are at right angles and the dot product is 0, regardless of the displacement, the work done by gravity is 0. You can also consider that the object is moving along an equipotential path, so there is no change in its potential energy due to gravity, so no work.
