What is the gravitational force exerted on an artificial satellite of mass 2000kg, if it moves in orbit with a radius of two terrestrial rays r = 2R,. . (R eath = 6380km, m land = 5.98 × 10 ^ 24kg)​

Answer 1

Gravitational force Fg = G m1 m2 / r2 = (6.673 x 10-11) (5.98 x 1024 kg) (2000 kg) / (2 • 6.38 x 106 m)2 = 4.90 x 103 N.
