A “synchronous” satellite, which always re- mains above the same point on a planet’s equator, is put in orbit about a planet similar to Jupiter. This planet rotates once every 6.5 h, has a mass of 1.8 × 1027 kg and a radius of 6.99 × 107 m. Given that G = 6.67 × 10?11 Nm2/kg2, calculate how far above Jupiter’s surface the satellite must be. Answer in units of m
