A) \[{{R}^{2}}\]
B) \[\frac{1}{{{R}^{2}}}\]
C) \[\frac{1}{R}\]
D) \[R\]
Correct Answer: D
Solution :
The capacitance of the conductor is \[C=\frac{q}{V}\] Potential on sphere of radius R is \[V=\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{q}{R}\] \[\therefore \] \[C=\frac{q\times 4\pi {{\varepsilon }_{0}}R}{q}=4\pi {{\varepsilon }_{0}}R\]
