O A composite spherical shell is made up of two materials having thermal conductivities K and 2 k respectively as shown in the diagram The temperature at the innermost surface is maintained at T whereas the temperature at the outermost surface is maintained at 10 T A B C and D are four points in the outer material such that AB BC CD The effective thermal resistance between the inner surface of the shell and the outer surface of the shell for the radial heat flow is 10T 1 7 8 KR 7 KR 487 KR In the certain process 100 Cal of boot are supplic 1 2 3 4 6 49 KR 1000 tom and at the come time
