A cylindrical capacitor is made of two thin-walled concentric cylinders. The inner cylinder has radius 5 mm , and the outer one a radius 11 mm . The common length of the cylinders is 160 m . What is the potential energy stored in this capacitor when a potential difference 6 V is

The  potential energy is

Explanation:

From the question we are told that

    The inner radius is  

      The outer radius is  

     The  common length is  

      The  potential  difference is  

Generally the capacitance of the cylindrical capacitor is mathematically represented as

Where   is the permitivity of free space with the values

and  k  is the dielectric constant  of the dielectric material here the  dielectric material is free space so  k  =   1

     Substituting values

The potential energy stored is mathematically represented as

substituting values
