Correct Option (d) 7A/3
Explanation:
The velocity of a particle executing SHM at any instant, is defined as the time rate of change of its displacement at that instant.
where, ω is angular frequency, A is amplitude and x is displacement of a particle.
Suppose that the new amplitude of the motion be A'.
Initial velocity of a particle performs SHM,
where, A is initial amplitude and ω is angular frequency,
Final velocity
