Question

Assertion (A): All bodies on being disturbed start vibrating with a definite frequency, thereby producing vibrations.

Reason (R): The vibrations produced by a disturbance are called free vibrations.

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.

Answer 1

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

Explanation:

Both statements are true. A disturbed body vibrates with a definite natural frequency, and vibrations caused by a disturbance are called free vibrations. The Reason gives a definition but does not explain why the body vibrates with a definite frequency.
