Problem: Why does a satellite in a circular orbit travel at a constant speed?A. There is no component of force acting along the direction of motion of the satellite.B. The net force acting on the satellite is zero.C. There is a force acting opposite to the direction of the motion of the satellite.D. The gravitational force acting on the satellite is balanced by the centrifugal force acting on thesatellite.

The gravitational force acting on the satellite provides a net force (Centripetal Force) directed towards the center of the orbit. Thus option B is not correct, because the net force on the satellite is equal to the centripetal force.
