Electric Field of a Charged Cylindrical Shell
A long cylindrical shell with inner radius a and outer radius b has a uniform volume charge density ρ. What is the magnitude of the electric field at a distance r from the cylinder’s axis, where a < r < b?
A
(ρr/2ε₀)[1-(a/r)²]
B
0
C
(ρ/2ε₀)(r²-a²)/r
D
(ρr/2ε₀)
