Question

at what height from the surface of earth the value of g is same as 16 km below the surface of earth

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.
