A net external force must act on the satellite tomake it change to a circular orbit that has a radius of 8.61 × 106 m. What work must the net external force do? Note that thework determined here is not the work Wift done by the satellite's engines to change the orbit. Instead, the work W isW = Wift + Wgravitational, where Wgravitational is the work done by the gravitational force.NumberiUnitseTextbook and MediaSave for LaterAttempts: 0 of 5 usedSubmit Answer...BỊNLBlaMacBook AirDD80888F7F8F9F10F2F3F4F6%232$&4789EYIII
