Gravitational force is given us fg, f subscript g, which is equal to g, that's capital g, times m, times m, divided by r squared, where r is the distance of the satellite from the center of the earth.
00:21
So distance from the center of the earth to the satellite to the satellite.
00:50
And m .e is the mass of the earth, so that's mass of earth, and m is the mass of the satellite.
01:10
Right, and g is our gravitational constant.
01:14
So to get the distance from the center of the earth, we need to know the radius of the earth or the distance from earth center to its surface, which we denote as, is r -e and r -e is 6 .38 times 10 to the power 6 meter.
01:40
So that means the total r or smaller should be this distance re plus the height of the satellite from the surface of the earth which is let's say age...
