## Homework Statement

A spherical shell with radius R and surface charge density σ is sandwiched between two infinite sheets with surface charge den- sities −σ and σ , as shown in Fig. 2.46. If the potential far to the right at x = +∞ is taken to be zero, what is the potential at the center of the sphere? At x = −∞?

## Homework Equations

P = kQ/R (where p is being used as electrical potential)

## The Attempt at a Solution

[/B]

P = kQ/R

For the sphere:

The electrical potential should be 0 because of symmetry.

So shouldn’t the electrical potential just be from the *sheets?

I’m not quite sure how to find that.
