An object in the vacuum of space orbits the earth at a fixed speed in a circular orbit several hundred miles above the earth. What can we conclude about the reaction force? I think the answer is B but not sure.

a) That there is no reaction force-the net force on the object is zero, so the reaction force is zero too.
b) The reaction force is a force that acts on the earth directed upward toward the object.
c) There is no reaction force- there’s a net force on the object, but zero reaction force because the object is out in space.
d) The reaction force is a normal force that acts upward from the Earth’s surface
