Given: G = 6.67259 ◊ 10−11 Nm2/kg2 .
A 602 kg geosynchronous satellite or-
bits a planet similar to Earth at a radius
1.98 ◊ 105 km from the planetís 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
011 (part 2 of 2) 10.0 points
What is the mass of this planet?
Answer in units of kg
