In this programming assignment, we intend to write a program to compute the capacitance of a cylindrical capacitor with different dielectrics. The formulae used for calculating the capacitance is:

$C=2{}_{}\frac{L}{ln(\frac{b}{a})}$

where $L$ is the length of cylinder, $a$ is the inner radius, and $b$ is the outer radius $($a should be less than b$)$ as shown in the image below:

The parameter $$ is the permittivity of the dielectric used between the two plates of the capacitor. This parameter is equal to the permittivity of free space multiplied by the relative permittivity $($Table $1)$ of the dielectric:

$={}_r{}_0$

Where, ${}_0$ is the permittivity of free space and it is equal to $8\mathrm{.}85{10}^{-12}\frac{C^2}{N}{m}^2$
