## Homework Statement

two thin conducting spheres, one inside the other. They are both centered about the same point. The outer sphere has a total charge Q and radius R2 and the inner sphere has a total charge -Q and radius R1.

The magnitude of the charges is Q = 500 nC, and the radii are R1 = 0.5 cm and R2 = 5.5 cm.

How much energy would you need to expend to move one electron from the outer sphere to the inner sphere?

## Homework Equations

W=kQ(-e)(1/R1- 1/R2)

## The Attempt at a Solution

W=kQ(-e)(1/R1- 1/R2)= 130.9
