A) \[\frac{1}{2}\]
B) \[\frac{2}{1}\]
C) \[\frac{4}{1}\]
D) \[\frac{1}{4}\]
Correct Answer: C
Solution :
Initially the rods are placed in vessels as shown below \[\frac{Q}{t}=\frac{({{\theta }_{1}}-{{\theta }_{2}})}{R}\]Þ\[{{\left( \frac{Q}{t} \right)}_{1}}=\frac{mL}{t}={{q}_{1}}L=\frac{(100-0)}{\frac{R}{2}}\] ... (i) Finally when rods are joined end to end as shown Þ \[{{\left( \frac{Q}{t} \right)}_{2}}=\frac{mL}{t}={{q}_{2}}L=\frac{(100-0)}{2R}\] ... (ii) From equation (i) and (ii), \[\frac{{{q}_{1}}}{{{q}_{2}}}=\frac{4}{1}\]You need to login to perform this action.
