Explanation : We know that two forces acting on the satellite.
The speed of the satellite and the force of the gravity on the satellite then the result , the satellite moves around the earth in a circular motion.
A satellite to move tangentially to a circular path, while revolving around the circular path because the centripetal force is acting on it.
So, we can say gravity is responsible for the motion of the satellite in a circular path.
