The work done by the force of the gravity on the satellite is zero. This is because, the force of gravity acts at right angle to the direction of motion of the satellite, and therefore, no displacement is caused in the direction of applied force, The force of gravity only varies the direction of motion of the satellite.

Hi there !!!
Work done = Force x displacement
In this case of moving satellite around the earth force due to gravity is perpendicular to the displacement of the satellite so when force and displacement are at 90° , W = 0
Also , no displacement is there in the direction of applied force.
Hence , work done is zero
