A) 2\[ohm\] and 7\[ohm\]
B) 3\[ohm\] and 6\[ohm\]
C) 3\[ohm\] and 9\[ohm\]
D) 5\[ohm\] and 4\[ohm\]
Correct Answer: B
Solution :
\[{{R}_{1}}+{{R}_{2}}=9\] and \[\frac{{{R}_{1}}{{R}_{2}}}{{{R}_{1}}+{{R}_{2}}}=2\] Þ \[{{R}_{1}}{{R}_{2}}=18\] \[{{R}_{1}}-{{R}_{2}}=\sqrt{{{({{R}_{1}}+{{R}_{2}})}^{2}}-4{{R}_{1}}{{R}_{2}}}=\sqrt{81-72}=3\] \[{{R}_{1}}=6\Omega ,\,{{R}_{2}}=3\Omega \]
