A) \[{{K}_{A}}=4{{K}_{B}}\]
B) \[{{K}_{A}}=2{{K}_{B}}\]
C) \[{{K}_{A}}={{K}_{B}}/2\]
D) \[{{K}_{A}}={{K}_{B}}/4\]
Correct Answer: D
Solution :
\[\frac{Q}{t}=\frac{KA\Delta \theta }{l}\Rightarrow \frac{{{K}_{A}}}{{{K}_{B}}}=\frac{{{A}_{B}}}{{{A}_{A}}}={{\left( \frac{{{r}_{B}}}{{{r}_{B}}} \right)}^{2}}=\frac{1}{4}\Rightarrow {{K}_{A}}=\frac{{{K}_{B}}}{4}\]You need to login to perform this action.
