360024 Assertion :
A force acts upon the earth revolving in a circular orbit about the sun and the work done on the earth due to this force is zero.
Reason :
The necessary centripetal force for circular motion of earth, comes from the gravitational force between earth and sun.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
