Which one of the following statements correctly explains why a satellite in uniform circular motion around the Earth does not fall onto the surface?
(a) The outward centrifugal force balances Earth’s gravity, so no net force acts on the satellite.
(b) The satellite experiences no gravitational force once it reaches orbital speed.
(c) The Earth’s gravitational pull continuously provides the centripetal force required for its curved path.
(d) The satellite continuously expels gases in the opposite direction to push itself away from Earth and stay in orbit.
