Finding the electic field inside a sphere

  1. Feb 19, 2009 #1
    1. The problem statement, all variables and given/known data

    what is the magnitude and direction of teh electric field just inside the sphere?
    givens: radius=10cm charge=.4uC

    2. Relevant equations

    E=kq/r^2

    3. The attempt at a solution
    i found that the electric field just outside the sphere is 360000vm^-1
    i just dont know how to find the field on the inside of the sphere
