A) \[\sqrt{{{R}_{1}}}\ :\ \sqrt{{{R}_{2}}}\]
B) \[{{R}_{1}}\ :\ {{R}_{2}}\]
C) \[R_{1}^{2}\ :\ R_{2}^{2}\]
D) \[R_{1}^{3}:\ R_{2}^{3}\]
Correct Answer: B
Solution :
Spheres have same potential i.e. \[k\frac{{{Q}_{1}}}{{{R}_{1}}}=k\frac{{{Q}_{2}}}{{{R}_{2}}}\]Þ \[\frac{{{Q}_{1}}}{{{Q}_{2}}}=\frac{{{R}_{1}}}{{{R}_{2}}}\]You need to login to perform this action.
