MHT CET 2024 2nd May Evening Shift | Simple Harmonic Motion Question 60 | Physics

For a body performing simple harmonic motion, its potential energy is $\mathrm{E}_{\mathrm{x}}$ at displacement x and $\mathrm{E}_{\mathrm{y}}$ at displacement y from mean position. The potential energy $E_0$ at displacement $(x+y)$ is

$\sqrt{\mathrm{E}_{\mathrm{x}}^2+\mathrm{E}_{\mathrm{y}}^2}$

$\sqrt{E_x-E_y}$

$E_x+E_y$

$E_x+E_y+2 \sqrt{E_x E_y}$
