Question
Consider a solid conducting sphere inside a hollow conducting shell.
The sphere has a radius of a while the shell has an inner radius of b and an outer radius of c. The sphere has a charge of +4Q on it while the shell has a charge of +6Q on it.
a. DERIVE, starting with Gauss
Consider a solid conducting sphere inside a hollow conducting shell. The sphere has a radius of a while the shell has an inner radius of b and an outer radius of c. The sphere has a charge of +4Q on it while the shell has a charge of +6Q on it. DERIVE, starting with Gauss's law, an expression for the electric field a distance r away from a point charge. Use that expression find the magnitude of the electric field for rExplanation / Answer
a) flux = q/e0
flux = E A = E 4 pi r^2
E = 1/4 pi e0 q/r^2
B) r<a, E = 0
a<r<b, E = 1/4 pi e0 4Q/r^2
b<r<c E = 0
r>c E = 1/4 pi e0 10 Q/r^2
