Finding total flux on Gaussian surface

  1. Feb 15, 2009 #1
    1. The problem statement, all variables and given/known data
    Consider the uniformly charged sphere with radius R. Q is the total charge inside the sphere. Find the total flux passing through the Gaussian surface (spherical shell) with radius r. (r<R)

    2. Relevant equations

    I I tried solving for the Electric Flux by simply dividing the Q by Empselon Knot thought this was too simple to be right, and as I suspected it, it was wrong.

    3. The attempt at a solution

    I used the formula for the electric flux but using Q divided by Empselon Knot and got it wrong. Maybe I'm not getting the concepts right.

    Welcome to PF!

    Hi phymateng! Welcome to PF! :smile:

    (it's called "espilon nought" … oh, and have an epsilon: ε :wink:)

    r < R, so the surface is inside the sphere, so it's not all of Q. :smile:

    Thank you. Yes, Q is the total charge inside the sphere and they are asking me to find the total flux passing through a gaussian surface of radius r inside the sphere. Radius of sphere is R. (so r<R)

    this solid sphere is a non conductor i assume..right?

    it doesn't say. So I assume it isn't.
