Previous Question: A composite block is made of slabs A, B, C, 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 (A) heat flow through A and E slabs are same. (B) heat flow through slab E is maximum. (C) temperature difference across slab E is smallest. (D) heat flow through C = heat flow through B + heat flow through D. Next Question: boy is pushing a ring of mass 2 kg and radius 0.5 m with a stick..The stick applies a force of 2N on the ring and rolls it without slipping with an acceleration of 0.3 m/s2. The coefficient of friction between the ground and the ring is large enough that rolling always occurs and the coefficeint of friction between the stick and the ring is (P/10). The value of P is
