Gauss's law

  1. Jan 21, 2008 #1
    1. The problem statement, all variables and given/known data

    What is the net electric flux through the the torus if a=-6 nC and b=60 nC ?


    2. Relevant equations

    Electric flux=Qin/E

    3. The attempt at a solution

    I solved with Qin being 6*10^-9 C as it is the charge inside and E0=8.85*10^-12. I got 678 for electric flux. But it is wrong.

    [tex]\epsilon_0 = 8.85*10^{-12}[/tex] not [tex]8.85*10^{-9}[/tex].

    This may be your problem. If it is not, show your work and we may be able to give you more in depth help.

    I put the right value for E0. But, I am not sure if the charge I am using is right or not. Is the charge inside 60nC, 6nC or net charge?

    Is the +60nC charge contained inside the surface of the solenoid?
