Question
Consider an uncharged, conducting hollow spherical shell. The electric field on the inside surface of the spherical shell is measured to be directed towards the inner shell wall and varies in magnitude over the spherical shell’s inside surface. It is known that the only charge in the hollow cavity inside the spherical shell is a point charge with magnitude q.What is the net electric flux through the spherical shell?
1)= 0
2) = 2q/e0
3) = q
4) = q/e0
5)= 2q
6) = q/2
7) = q/2e0
What can you say about the charge distribution on the outside surface of the spherical shell?
1. The charge distribution is negative and is uniform.
2. The charge distribution is positive and is uniform.
3. The charge distribution is negative and is not uniform.
4. The charge distribution is positive and is not uniform.
5. The charge distribution is zero.
Explanation / Answer
a) Guass's law. its is q/epsilon0. b) With the Gaussian surface that is in between the inner and outer surface of the shell. Flux = zero. (E=0). so charge on the inner surface is -q. the shell is uncharged, so the charge on the outer surface is q. so the charge is positive. cause the shell is a sphere, and is the same at any direction. so the distribution is uniform. so 2.)
