A) \[950\,\Omega \]and \[9150\,\Omega \]
B) \[900\,\Omega \]and\[9950\,\Omega \]
C) \[900\,\Omega \]and\[9900\,\Omega \]
D) \[950\,\Omega \]and \[9000\,\Omega \]
E) \[950\,\Omega \]and\[9950\,\Omega \]
Correct Answer: D
Solution :
Given: \[V=1\]volt \[{{I}_{g}}=1\,mA\] \[=1\times {{10}^{-3}}A\] Resistance of a galvanometer \[G=50\,\Omega \] \[\therefore \] \[{{R}_{T}}=\frac{V}{{{I}_{g}}}-G\] or \[{{R}_{T}}=\frac{1}{{{10}^{-3}}}-50\] or \[{{R}_{1}}=950\,\Omega \] AISO \[{{R}_{2}}=\frac{10}{{{10}^{-3}}}-50\] \[=9950\,\Omega \] Additional resistance for attaining \[10V=9950-950\] \[=9000\,\Omega \] Hence, \[{{R}_{1}}=950\,\Omega ,{{R}_{2}}=9000\,\Omega \]
