(b) A spherical planet has mass 6.00 × 1024 kg and radius 6.40 × 106 m.
The planet may be assumed to be isolated in space with its mass concentrated at its centre.
A satellite of mass 340 kg is in a circular orbit about the planet at a height 9.00 × 105 m above
its surface.
For the satellite:
(i) show that its orbital speed is 7.4 × 103 m s–1
