Question

a satellite of mass m is moving round the earth with a speed of v .state the work done by the force of gravity on satellite.

Answer 1

Answer:

The work done by the gravitational force depends only on its initial and its final position, and not on the actual path followed.

So, in this case,

The force of the earth acting on the satellite is perpendicular to its direction of motion, so the work done by the force of gravity on earth is equal to zero(0)
