A small hole of radius 1 cm is made in a blackened spherical shell of radius 2m. Inside the shell we have another concentric blackened sphere of radius 1m. The inner sphere is perfectly conducting Sun light of intensity 1600 W/m falls through the hole on the inner shell in a direction perpendicular to the surface. The shell is also perfectly conducting and is located in vacuum. No radiations are falling from sun on the outer surface of the shell. Choose the correct statement(s):A. The radiation spectrum coming out from the hole will be same as that of a black body at the temperature of the inner sphere.B. The steady state temperature of the sphere is close to 30 KC. The steady state temperature of the shell is close to 20 KD. The steady state temperature of the shell is close to 10 K
