A) \[{{K}_{1}}+{{K}_{2}}\]
B) \[\frac{{{K}_{1}}+8{{K}_{2}}}{9}\]
C) \[\frac{{{K}_{1}}{{K}_{2}}}{{{K}_{1}}+{{K}_{2}}}\]
D) \[\frac{8{{K}_{1}}+{{K}_{2}}}{9}\]
Correct Answer: B
Solution :
\[\frac{1}{\operatorname{R}{{ & }_{eq}}}=\frac{1}{{{R}_{1}}}+\frac{1}{{{R}_{2}}}\] \[\frac{{{K}_{eq}}(9\pi {{R}^{2}})}{L}=\frac{{{K}_{1}}\pi {{R}^{2}}}{L}+\frac{{{K}_{2}}8\pi {{R}^{2}}}{L}\] \[{{K}_{eq}}\,\,=\,\,\frac{{{K}_{1}}+8{{K}_{2}}}{9}\]You need to login to perform this action.
