Electric Flux through a Pyramid

  1. Sep 22, 2008 #1
    1. The problem statement, all variables and given/known data
    A pyramid with horizontal square base, 6.00 m on each side, and a hieght of 4.00 m is placed in a vertical electric field of 52.0 N/C. Calculate the total electric flux through the pyramid's four slanted surfaces.


    2. Relevant equations

    Phi = E*A*cos(theta)

    3. The attempt at a solution

    i found the length of the of the hypotenuse and found the area of the side and im having trouble figuring out the angle of the area vector and the electric field vector

    Hint: what is the relationship between the flux through the four slanted surfaces, and the flux through the base? :wink:

    think of flux as flowing water. what is the net flow of water through the walls of the pyramid?
