Assertion A load when lifted vertically up requires greater effort than to roll the same load up the ramp. Reason The work done in lifting the load vertically up is less.

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

Correct answer: Assertion is correct but Reason is incorrect

Solution

Lifting vertically needs a larger force than pushing the same load up a ramp, so the assertion is correct. But the reason is wrong because the work done in lifting vertically is not less; ideally, it is the same as the work done along the ramp (ignoring friction).
