Question

Assertion :For an inclined plane mechanical advantage increases as the angle of inclination decreases. Reason: Angle of inclination increases with respect to vertical height of inclined plane.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Assertion is incorrect but Reason is correct

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Given :

Assertion

For an inclined plane mechanical advantage increases as the angle of inclination decreases.

Reason

Angle of inclination increases with respect to vertical height of inclined plane.

Solution :

To find the ideal mechanical advantage of an inclined plane, divide the length of the slope by its height. An inclined plane produces a mechanical advantage to decrease the amount of force needed to move an object to a certain height; it also increases the distance the object must move. Hence we can say that both Assertion and Reason are correct.

The Correct Opt = A
