Question

Assertion (A): The amplitude of damped vibrations generally decreases with time and at the end vibration stops.

Reason (R): In each vibrations there is a progressive loss of energy.

Options

• 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 and Reason (R) is the correct explanation of Assertion.

Explanation:

Both statements are true. Resistive forces cause the vibrating body to lose energy progressively. As its energy decreases, the amplitude becomes smaller and the vibrations eventually stop.
