Answer #1

This problem is solved with help of concept of circular motion. The earth will attract the satellite orbiting around the earth. The gravitational attraction will be balance by the centrifugal force produced by orbiting satellite. The force will be balance. So the gravitational attraction is equal to centrifugal force.

Answer: the velocity of satellite is 8 km/s.
