Two cylindrical copper vessels A and B have circular bases of thickness 'd' and '2d' respectively. Their diameters are R and 2R respectively. The heights of the standing water in vessels are 2h and h respectively. Both A and B are placed on hot plate having constant temperature T 0 ​ > 10 0 ∘ C . When the water in both vessels starts to boil,
