Practicing Success
A research satellite of mass 200 kg circle the earth in an orbit of average radius 3R/2, where R is the radius of the earth. Assuming the gravitational pull on the mass of 1 kg on the earth's surface to be 10 N, the pull on the satellite will be : |
871 N 1212 N 960 N 1280 N |
871 N |
\(g_{eff} = g (1 + \frac{h}{R})^{-2}\) \(g_{eff} = g (1 + \frac{1}{2})^{-2}\) \(g_{eff} = \frac{4}{9}g\) \(F = mg_{eff} = 200 * \frac{4}{9}*9.8\) F = 871 N |
