Two identical spheres `S_(1)` and `S_(2)` out of which `S_(1)` is placed on the insulating horizontal surface and `S_(2)` hangs from an insulating string. If both were given same quantity of heat. Then:

Consider two identical iron spheres , one which lie on a thermally insulating plate, while the other hangs from an insulatory thread. Equal amount of heat is supplied to the two spheres, then

Two metallic spheres S_1 and S_2 are made of the same material and have got identical surface finish. The mass of S_1 is thrice that of S_2 . Both the spheres are heated to the same high temperature and placed in the same room having lower temperature but are thermally insulated from each other. the ratio of the initial rate of cooling of S_1 to that of S_2 is (a)1/3 (b)1/(sqrt3) (c) (sqrt3)/1 (d) (1/3)^(1/3)

Two metallic spheres S_1 and S_2 are made of the same material and have got identical surface finish. The mass of S_1 is thrice that of S_2 . Both the spheres are heated to the same high temperature and placed in the same room having lower temperature but are thermally insulated from each other. the ratio of the initial rate of cooling of S_1 to that of S_2 is (a)1/3 (b)1/(sqrt3) (c) (sqrt3)/1 (d) (1/3)^(1/3)

Both the spheres are heated to the same high temperature and placed in the same room having lower temperature but are thermally insulated from each other. the ratio of the initial rate of cooling of S_1 to that of S_2 is

Two metallic spheres S_1 and S_2 are mode of the same material and have got identical surface finish. The mass of S_1 is thrice that of S_2. Both the spheres are heated to the same high temperature and placed in the same room having lower temperature but are thermally insulted from each other. The ratio of the initial rate of coiling of S_1 to that of S_2 is

S_(1) and S_(2) are two equipotential surfaces on which the potentials are not equal

S_(1) and S_(2) are two equipotential surfaces on which the potentials are not equal

Two metallic spheres S_(1) and S_(2) made of same material have identical surface finish. The mass of S_(1) is 3 times that of S_(2) . Both are heated to same temperature and are placed in same surroundings. Then ratio of their initial rates of fall of temperature will be
