Question

a positively charged particle is at a distance R/2 from center of an uncharged thin, conducting, spherical shell of radius R. sketch the electric field lines set up by this arrangement both inside and outside the shell

Answer 1

Hello! I'm not sure about this one, but I can venture a guess.

The conducting shell is a shell that can move charges freely as they are forced to by the magnetic field.

Here is the shell and charge:

Answer 2

The electric field from the positive charge - the same field that attract free moving electrons of the shell - is much stronger closer to the charge.

Field lines go away from positive, and towards negative. The only negative charge is in the shell. The negative charges repel each other, but are attracted by the positive. So they are somewhat spread out, clumping near the positive charge.

And I think the field will be nearly \(0\) outside the shell, but I'm not sure.

Does any of that sound right?
