Question

Geosynchronous satellites orbit the Earth at a distance of 42,000 km from the Earth’s center. Their angular velocity at this height is the same as the rotation of the Earth, so they appear stationary at certain locations in the sky. What is the force acting on a 3000 kg satellite at this height?

A. 300 N B.100 N C.4,000 N D 3,000 N E 666 N
