A) \[\frac{R}{{{n}^{2}}}\]
B) \[nR\]
C) \[\frac{R}{n}\]
D) \[{{n}^{2}}R\]
Correct Answer: D
Solution :
\[\frac{{{R}_{2}}}{{{R}_{1}}}=\frac{l_{2}^{2}}{l_{1}^{2}}\] \[=\frac{{{n}^{2}}l_{1}^{2}}{l_{1}^{2}}\] \[\frac{{{R}_{2}}}{{{R}_{1}}}={{n}^{2}}\] \[{{R}_{2}}={{n}^{2}}{{R}_{1}}\]You need to login to perform this action.
