1.	Assertion: A child in a garden swing periodically presses his feet against the ground to maintain the oscillations. Reason: All free oscillations eventually die out because of the ever present damping force.
Answer» If both assertion and reson are TRUE and reason is the correct EXPLANATION of assertion If both assertion and reason are true but reason is not the correct explanation of assertion. If assertion is true but reason is false. If both assertion and reason are false. Solution :In forced PERIODIC oscillation, the system oscillates not with its natural frequency but at the frequency of the external agency, the free OSCILLATIONS die out due to damping.
