A satellite is in a circular orbit around the Earth at an altitude of 450 km above the surface. What is the speed of the satellite in its orbit? (G = 6.674 x 10^-11 Nm^2/kg^2, ME = 5.974 x 10^24 kg, RE = 6378 km) 8078 m/s 7510 m/s 7641 m/s 6908 m/s 7932 m/s 8120 m/s

A satellite is revolving round the earth in circular orbit at some height above surface of earth. It takes $5.26 \times 10^{3}$ seconds to complete a revolution while its centripetal acceleration is $9.92 \mathrm{~m} / \mathrm{s}^{2}$. Height of satellite above surface of earth is (Radius of earth $6.37 \times 10^{6} \mathrm{~m}$ ) (a) $70 \mathrm{~km}$ (b) $120 \mathrm{~km}$ (c) $170 \mathrm{~km}$ (d) $220 \mathrm{~km}$
