Solution

The correct option is C

both spheres will cool at the same rate for all values of T


The rate at which a sphere radiates heat depends upon its material, its surface area and its temperature. Therefore, the solid and the hollow spheres, being of the same material and of the same size and at the same temperature, will cool at the same rate. Hence, the correct choice is (c).
