Asatellite moves at a constant speed in a circular orbit about the center of the earth and near the surface of the earth. assume that the acceleration of gravity on this satellite is g = 9.81 m/s2 and that the radius of the earth is 6370 km. how long does it take for this satellite to make one complete revolution around the earth?

Explanation:

The period of a satellite orbiting at a constant speed is given by:

Here, is for one revolution, r is the radius of the circular motion and v is the speed of the satellite. Gravity acts on the satellite, which is responsible for the centripetal force.

Replacing (2) in (1):

probably not if net force is zero

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
