Question
A composite block is made of slabs $\mathrm{A}, \mathrm{B}, \mathrm{C}, \mathrm{D}$ and E of different thermal conductivities (given in terms of a constant K ) and sizes (given in terms of length, L ) as shown in the figure. All slabs are of same width. Heat 'Q' flows only from left to right through the blocks. Then in steady state
