1.	Two metallic sphere A and B are made of same material and have got identical surface finish. The mass of sphere A is four times that of B. Both the spheres are heated to the same temperature and placed in a room having lower temperature but thermally insulated from each other.
Answer» The ratio of heat loss of A to that of B is `2^(4//3)` The ratio of heat loss of A to that of B is `2^(2//3)` The ratio of the INITIAL RATE of cooling of A to that of B is `2^(-2//3)` The ratio of the initial rate of cooling of A to that of B is `2^(-4//3)` Answer :A::C
