Question

Calculate the gravitational force between the Earth and a satellite of mass 100 kg (Mass of Earth - 6x 1024 and 66.673 x 1011 Distance from center of earth to the center of the satellite - 12 x 107 m) Attach File Brourse My Computer Browse Content Collection

Answer 1

Given:

$m=100\ \text{kg}\\ M=6\times10^{24}\ \text{kg}\\ G=6.673\times10^{-11}\ \text{Nm}^2/\text{kg}^2\\ r=1.2\times10^{7}\ \text m$

The gravitational force between the Earth and Satellite is,

$F=\frac{GMm}{r^2}\\ =\frac{6.673\times10^{-11}\times6\times10^{24}\times100}{(1.2\times10^{7})^2}\ \text N\\ =278.0\ \text N$
