The minimum and maximum distances of a satellite from the
centre of the earth are 2R and 4R, respectively, where R is the
radius of earth and M is the mass of the earth.
The minimum and maximum speeds
- \(\sqrt{\frac{G M}{9 R}}, \sqrt{\frac{2 G M}{R}}\)
- \(\sqrt{\frac{G M}{5 R}}, \sqrt{\frac{3 G M}{2 R}}\)
- \(\sqrt{\frac{G M}{6 R}}, \sqrt{\frac{2 G M}{3 R}}\)
- \(\sqrt{\frac{G M}{3 R}}, \sqrt{\frac{5 G M}{2 R}}\)
Answer
(C) G M 6 R , 2 G M 3 R
