Gaussian Shell and net electric field

  1. Feb 7, 2017 #1
    1. The problem statement, all variables and given/known data
    upload_2017-2-7_10-46-52.png

    2. Relevant equations
    σ=q/(4πr^2)→q=σ(4πr^2)
    E=q/(4πEod^2)
    E=(4πr^2σ)/(4πEod^2)


    3. The attempt at a solution
    So the first thing that i could include was that the point p was inside Shell 1 and therefor would not be affected by Shell 1.

    So it should be a fairly simple plug in the variables sort of problem
    E=(4π(.017m)^2*(3.3E-6))/(4π(8.99E-9C)(0.104m-0.024m)^2)
    E=16.5757 N/C

    Looks ok. Is the answer rejected?

    I used 899E-9 as Coulomb's constant. I believe that was my mistake.

    That's the one thing I did not check.

    Silly me.
