# Electric Field of Nonconducting Solid Sphere

## Homework Statement

A nonconducting solid sphere of radius 2.30 cm carries a uniformly distributed positive charge of 8.00×10-9 C. Calculate the magnitude of electric field at 1.60 cm away from the center of sphere

E=kqr/R^3

## The Attempt at a Solution

(8.99x10^9)(8x10^-9)(.16)/(.23^2)=217.53 N/C

Clearly this solution is not correct, but I do not understand why using the formula did not work.
