Field to Potential Conversion

  1. Mar 30, 2010 #1
    Consider a uniformly charged sphere of radius R and total charge Q. The electrical field E(out) outside the sphere (r>R) is simply that of a point charge Q. Gauss's law was used to find E(in) inside the sphere(r<R) is radially ouwards with the field strength

    Ein = (1/4*pi*epsilon0)*(Q/R^3)*r

    A) Graph E vs r for 0<r<3R
    b) The electric potential Vout outside the sphere is that of a point charge Q. Find an expression for the electric potential Vin at position r inside the sphere.
    c)What is the ration Vcentre/Vsurface
    d) Graph V vs r for 0<r<3R
