an artificial satellite is orbiting at 500 km above the earth's surface. take the radius of earth as 6.5 * 10^{6} .
- find the acceleration due to gravity at any point along the satellite path.
- What is the centripetal acceleration of the satellite?

g`=g(1+h)-2

=9.8(1+5006.5*10

^{6})

^{-2 centripetal acc =GMm}
