What do orbiting satellites and the orbit of the moon around the Earth have in common?

A. Velocity

B. Central-force motion

C. Friction

D. Parallel-force motion

Option (B)

Explanation:

All the satellites moves around the central mass due to the two forces:

1. Gravitational force acting between the central mass and the satellites.

2. Centrifugal force acting on the satellite due to the circular motion.

The magnitude of both the forces is same but the direction is opposite to each other.

The direction of gravitational force is towards the centre of the central mass and the centrifugal force is opposite the direction of gravitational force.

Both the forces acting radially.

B. Central-force motion
