A particle performs SHM of amplitude A along a straight line. When it is at distance `sqrt(3)/2` A from mean position, its kinetic energy gets increased by an amount `1/2momega^(2)A^(2)` due to an impulsive force. Then its new amplitude becomes.
A. `(sqrt(5))/(2)A`
B. `(sqrt(3))/(2)A`
C. `sqrt(2)A`
D. `sqrt(5)A`
