Question : Which force is responsible for the motion of the moon around the Earth?
Option 1: Van der Waals
Option 2: Centrifugal
Option 3: Frictional
Option 4: Centripetal
Correct Answer: Centripetal
Solution : The correct answer is Centripetal.
The centripetal gravitational force is responsible for the moon's orbit around the Earth. The centripetal force needed to maintain planets in orbit around the sun is provided by gravitational pull, and it is also responsible for satellites orbiting the Earth. A lunar revolution takes around a month to complete.
