The class is about Electricity and magnetism. The website wants exactly the perfect answer and in the same metric system units that are stated on the calculators that are on the picture for the questions, if not, it'll not, it'll mark it wrong.

Cylindrical Capacitor The long cylindrical capacitor shown above consists of four concentric metal cylinders with radii Ra = 1.7 cm, Re = 3.5 cm, Rb = 5.2 cm, and Ra = 7.6 cm. The cylinders of radii Ry and Re are joined by metal strips. Determine the capacitance C per unit length of this system, given the external leads are connected at Ra and Ra. 5 010 C= F/m abc sin(x) Ox10 Submit Reset Reset All .Put charge density +) on the innermost conductor and charge density - on the outermost conductor. The goal is to find the resulting potential difference V between the innermost and outermost conductors, since C = 1/V is the desired capacitance per unit length. .If charge density ) is placed on the innermost conductor of radius Ra, what is the charge density induced on the conductor of radius Rb? On the conductor of radius Rc? .Use Gauss' law to find the electric field everywhere first. (What is the electric field inside an empty cavity within a conductor, as in the region between Rb and Re?) Once you have found the electric field, integrate E between Ra and Ra to find the potential difference between the innermost and outermost conductors
