Two spherical black bodies of radii '$$r_1$$' and '$$r_2$$' at temperature '$$\mathrm{T}_1$$' and '$$\mathrm{T}_2$$' respectively radiate power in the ratio $$1: 2$$ Then $$r_1: r_2$$ is

$$\frac{1}{2}\left(\frac{\mathrm{T}_2}{\mathrm{~T}_1}\right)^4$$

$$\frac{1}{\sqrt{2}}\left(\frac{\mathrm{T}_2}{\mathrm{~T}_1}\right)^2$$

$$2\left(\frac{\mathrm{T}_1}{\mathrm{~T}_2}\right)^4$$

$$2\left(\frac{T_1}{T_2}\right)^2$$

For a particle executing S.H.M., its potential energy is 8 times its kinetic energy at certain displacement '$$x$$' from the mean position. If '$$A$$' is the amplitude of S.H.M the value of '$$x$$' is

$$\frac{\mathrm{A} \sqrt{2}}{3}$$

$$\mathrm{A} \sqrt{3}$$

$$\frac{2 \sqrt{2} \mathrm{~A}}{3}$$

$$\frac{\mathrm{A}}{\sqrt{2}}$$

The maximum kinetic energies of photoelectrons emitted are $$\mathrm{K}_1$$ and $$\mathrm{K}_2$$ when lights of wavelengths $$\lambda_1$$ and $$\lambda_2$$ are incident on a metallic surface. If $$\lambda_1=3 \lambda_2$$ then

$$\mathrm{K}_1=\frac{\mathrm{K}_2}{3}$$

$$\mathrm{K}_1<\frac{\mathrm{K}_2}{3}$$

$$\mathrm{K}_1=3 \mathrm{K}_2$$

$$3 \mathrm{K}_1=2 \mathrm{K}_2$$
