Two identical conducting rods are first connected independently to two vessels, one containing water at $$1000C$$ and the other containing ice at $$00C$$. In the second case, the rods are joined $$end-to-end$$ and connected to the same vessels. Let $$q1$$ and $$q2$$ $$gs-1$$ be the rate of melting of ice in two cases, respectively. The ratio of $$q1q2is$$

Question

Two identical conducting rods are first connected independently to two vessels, one containing water at $$1000C$$ and the other containing ice at $$00C$$. In the second case, the rods are joined $$end-to-end$$ and connected to the same vessels. Let $$q1$$ and $$q2$$ $$gs-1$$ be the rate of melting of ice in two cases, respectively. The ratio of  $$q1q2is$$

Initially the rods are in parallel,  $$Qt=$$θ$$1$$−θ$$2R$$⇒ $$Qt1=mLt=q1L=(100$$−$$0)R/2$$                   …(i)Finally$$ when rods are in series,⇒ $$Qt2=mLt=q2L=(100$$−$$0)2R$$             …$$(ii)From$$ Eqs. $$(i) and (ii), we $$getq1q2=41$$
