There are two spherical balls A and B of the same material with same surface, but the diameter of A is half that of B . If A and B are heated to the same temperature and then allowed to cool, then

Two spheres A and B have the same radii but the capacity of A is greater than that of B . The surfaces of both are painted black. They are heated to the same temperature and allowed to cool in vacuum. Then,

Two spheres A and B have radius but the heat capacity of A is greater than that of B. The surfaces of both are painted black. They are heated to the same temperature and allowed to cool. Then initially

Two spheres A and B have radius but the heat capacity of A is greater than that of B. The surfaces of both are painted black. They are heated to the same temperature and allowed to cool. Then initially

Two metalic spheres p and Q are made of same material have same smoothness but the weight of p is 8 times that of Q if the two are heated to same temperature and left to cool then the ratio of rate of cooling of Q to that of p is
