NY75 C 2 3 33 C Two spheres of different materials one having radius double of other and wall thickness 1 4 of other are filled with ice If time required to completely melt the ice is 25 min for larger radius sphere and 16 min for smaller radius sphere then ratio of thermal conduction coefficient for material of larger radius to that of thermal conduction coefficient for mate rial of smaller radius sphere will be 1 4 5 2 5 4 3 8 25 1 1 25 It is placed in a furnace and it is observed that RPMT 2010 RPMT 2010
