A particle executing a simple harmonic motion of period `2s`. When it is at its extreme displacement from its mean postion, it receives an additional energy equal to what it had in its mean position. Due to this, in its subsequent motion-

A

its amplitude will change and become equal to `sqrt2` tims its previous amplitude

B

its peridic time will become doubled i.e., `4s`

C

its potential energy will be decreased

D

it will continue to execute simple harmonic motion of the same amplitude and period as before receiving the additional energy
