Given: G = 6.67259 × 10−11 Nm2/kg2 .
A 1050 kg geosynchronous satellite or-
bits a planet similar to Earth at a radius
1.96 × 105 km from the planet’s center. Its
angular speed at this radius is the same as the
rotational speed of the Earth, and so they ap-
pear stationary in the sky. That is, the period
of the satellite is 24 h .
What is the force acting on this satellite?
Answer in units of N
What is the mass of this planet?
Answer in units of kg
