A) the permittivity constant
B) the radius of the inner conductor
C) the amount of charge on the conductors
D) the radius of the outer conductor
E) the length of the cylinde

Answer:

Capacitance of cylindrical capacitor does not depends on the amount of charge on the conductors

Explanation:

Consider a cylindrical capacitor of length L, inner radius R₁ and outer radius R₂, permitivity ε₀ constant then capacitance of cylindrical capacitor is given by:

[tex]C=\frac{2\pi \epsilon_{o}L}{ln\frac{R_{2} }{R_{1}} }[/tex]

From this equation it is clear that capacitance of cylindrical capacitor is independent of the amount of charge on the conductors where as directly  proportional permitivity constant and length of cylinder where as inversely proportional to natural log of ratio of  R₂ and R₁
