A body is executing a linear S.H.M. Its potential energies at the displacement '$$\mathrm{x}$$' and '$$\mathrm{y}$$' are '$$\mathrm{E}_1$$' and '$$E_2$$' respectively. Its potential energy at displacement $$(\mathrm{x}+\mathrm{y})$$ will be

$$\mathrm{E}_1+\mathrm{E}_2$$

$$\left(\sqrt{\mathrm{E}_1}+\sqrt{\mathrm{E}_2}\right)^2$$

$$\quad \mathrm{E}_1-\mathrm{E}_2$$

$$\left(\sqrt{\mathrm{E}_2}-\sqrt{\mathrm{E}_1}\right)^2$$
