Question

what is work done by the earth gravitional force in keeping a satelite orbiting at a height of 36500 km above the surface of earth

Answer 1

thank you for asking the question !!!

as we know 36500 km above the earth, the work done by the centripetal force is "zero" and gravitation force is also "zero" at that point so there will be no work needed by earth.

i hope it will help.
