Thanks! I figure out that I should get Qmax first and then plug in 1.5e-2 and 0.1e-3 to find the Vmax.

I tried to relate to the E field by using Gauss's Law, and I get E = λ/2πrε0. Integrate E, I get V= (λ/2πε0)ln(r), and then I don't know where I should integrate from. Should I integrate from 1.5e-2m to 0.1e-3m or do I get r by plugging the dielectric strength into the equation of E?

Homework Statement A detector of radiation called a Geiger-Muller counter consists of a closed, hollow, conducting cylinder with a fine wire along its axis. Suppose that the internal diameter of the cylinder is 3.00 cm and that the wire along the axis has a diameter of 0.2 mm. If the dielectric...

I was doing my physics homework and I sometimes stuck on some problem. Every time I search for explanations, this forums offers a lot help and people here did great job in explaining a concept explicitly. Love to be here!
