Homework Help: Electric Field of Nonconducting Solid Sphere

  1. Sep 27, 2011 #1
    1. The problem statement, all variables and given/known data

    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


    2. Relevant equations

    E=kqr/R^3



    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.
