A solid conducting sphere of radius \[{{R}_{\text{1}}}\] is surrounded by another concentric hollow conducting sphere of radius \[{{R}_{\text{2}}}\]. The capacitance of this assembly is proportional to [MP PET 2001; UPSEAT 2001]

\[\frac{{{R}_{2}}-{{R}_{1}}}{{{R}_{1}}{{R}_{2}}}\]

\[\frac{{{R}_{2}}+{{R}_{1}}}{{{R}_{1}}{{R}_{2}}}\]

\[\frac{{{R}_{1}}{{R}_{2}}}{{{R}_{1}}+{{R}_{2}}}\]

\[\frac{{{R}_{1}}{{R}_{2}}}{{{R}_{2}}-{{R}_{1}}}\]
