JEE MAIN - Physics (2024 - 4th April Evening Shift - No. 7)
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:

$$E / \sqrt{2}$$
$$2 E$$
$$E \sqrt{2}$$
$$E$$
Explanation
$$\because \quad E=\frac{1}{2} k A^2$$
Here energy depends on $$A$$ and $$k$$ and not on mass.
