Question

Assertion (A): A machine having mechanical advantage greater than 1, gives gain in speed.

Reason (R): A machine having mechanical advantage less than 1, acts as a force multiplier.

विकल्प

• Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion.

• Both Assertion (A) and Reason (R) are true but Reason (R) is not the correction explanation of Assertion.

• Assertion (A) is false, but Reason (R) is true.

• Assertion (A) is true, but Reason (R) is false.

• Both Assertion (A) and Reason (R) are false.

Answer 1

Both Assertion (A) and Reason (R) are false.

Explanation:

Assertion (A) is false because a machine with a mechanical advantage greater than 1 multiplies force, not speed.

Reason (R) is false because a machine with a mechanical advantage less than 1 multiplies speed, not force.
