Assertion Pulling a lawn roller is easier than pushing it. Reason pulling decreases the apparent weight as the vertical component of the pulling force acts upward.

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: Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.

Solution

Pulling a roller usually has an upward component, which reduces the normal reaction and therefore the frictional force. Pushing tends to add a downward component, increasing the normal reaction and making motion harder.
