Current Attempt in Progress A 6260-kg satellite is in a circular earth orbit that has a radius of 3.17 × 10' m. A net external force must act on the satellite to make it change to a circular orbit that has a radius of 8.61 x 10° m. VWhat work must the net external force do? Note that the work determined here is not the work Wift done by the satellite's engines to change the orbit. Instead, the work W is W = Wift + Weravitational, where Wgravitational is the work done by the gravitational force.
