Calculate the circular speed that an artificial satellite of Jupiter should have, circling its surface at a distance of 2000 km

Calculate the circular speed that an artificial satellite of Jupiter should have, circling its surface at a distance of 2000 km. Jupiter’s mass is 1.9 * 10 ^ 27 kg, radius – 71,000 km.

decision
v = √GM / (R + h); v ^ 2 = 6/67 * 10 ^ -11 * 1.9 * 10 ^ 27 / 7.12 * 10 ^ 7; v = 42 • 10 ^ 3 (m / s) = 42 (km / s).
