Electrostatics: Charge density in a coaxial cable.
Not what you're looking for?
We have a long coaxial cable with an inner solid wire of radius a and outer
metal shell of radius b. On the inner wire, the volume charge density is given by ks2 .
On the outer shell, the linear charge density (along the axis) is given by λ.
(a) Draw a picture that illustrates this arrangement.
(b) What is the linear charge density λ that will give E = 0 outside the cable?
