Question
What provides the necessary centripetal force to the Earth so that it keeps revolving around the Sun in the same orbit?
- Gravitational force
- Muscular force
- Frictional force
- Tension
Hint:
It is the inward force from the sun which keeps the earth in its orbit.
The correct answer is: Gravitational force
The gravitational attraction of the Sun acts as a centripetal force on the Earth producing the centripetal acceleration of the orbital motion.
