PHXI06:WORK ENERGY AND POWER

355408 Assertion :
The work done in bringing a body down from the top to the base along a frictionless inclined plane is the same as the work done in bringing it down the vertical side.
Reason :
The gravitational force on the body along the inclined plane is the same as that along the vertical side.

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.
