Energy in SHM

In simple harmonic motion, the total mechanical energy of given system is $E$ . If mass of oscillating particle $P$ is doubled then the new energy of the system for same amplitude is:

Show answer and solution

Answer: (d)

$E = \dfrac{1}{2}kA^2$ for the spring-mass system.
Doubling $m$ changes $\omega$ but not $k$ or $A$ .
So the energy stays $E$ ; the answer is (d).
