# Electric Field?

## Homework Statement

This is a two part problem:

3- A conducting spherical shell of radius 19 cm carries a net charge of −8.15 μC uniformly distributed on its surface. Find the electric field at points just outside the shell. (Take the radially outward direction to be positive.) Answer in units of N/C.

## Homework Equations

E = k$$\frac{F}{q}$$

## The Attempt at a Solution

E=k$$\frac{8.15x10^-6 C}{(.19 m)^2}$$=
E= 2.03x10^6$$\frac{Nm}{C}$$

4- Find the electric field at points inside the shell. Answer in units of N/C.

I am not sure how to do this part.
