Question

Gauss's law applied to spherical conducting shells...

The figure shows a spherical conducting shell, inner radius a, and outer radius b, with a point charge +Q inside. In case (1) the point charge is at the center of the shell, and in case (2) it is off-center. In the figures, draw a typical electric field line starting from the charge, extending vertically in the diagram and ending where you think it should end.

Explanation / Answer

the electric field beyond the internal surface is 0, this means that all field lines will start in the charge Q, and end in the surface "a", so you just need draw lines from the charge to the small circle
