Question

In the usual rotation the acceleration due to gravity. at a height h from the surface of the earth is .......

Answer 1

Answer:

At a point above the surface of earth, the gravitational potential is -5.12 × 107J/kg and the acceleration due to gravity is 6.4 m/s2. Assuming the mean radius of the earth to be 6400 km, calculate the height of this point above the earth's surface.
