Find the initial surface charge density of outer conductor

Reference no: EM13516305

The electric field strength just outside the outer conductor of a coaxial cable of outer radius of 0.2cm is E=7200N/C directed inward. The 0.4cm diameter center conductor is then charged such that this electric field reverses to outward with a strength of 2800N/C.

a) What is the initial surface charge density of the outer conductor?

b) What is the surface charge density on the outer conductor after the center conductor has been charged?

c) What is the linear charge density added to the center conductor?

d) What is the net charge on a 5m section of the coaxial cable?

e) After the center conductor has been charged, accurately plot the electric field strength as a function of radius from r=0cm to r=1cm (the outer conductor has a thickness of 0.02cm)
