1. The problem statement, all variables and given/known data base of pyramid is a 6m x 6m square height of pyramid is 4meters. a 52 N/C E field orthogonal to the base of the pyramid 2. Relevant equations EA cos theta 3. The attempt at a solution if flux through base = EAcos theta = 52 (36m^2) cos(0) = 1872 N m^2 / C Area of face of pyramid is 1/2 base x height = (.5)(6)(4) = 12 angle of normal to surface and E field is cos-1(3/5) Why is flux through each surface not equal to the following: so flux through one surface is = 52 N/C x 12m x cos(53.1) = 374.6 374.6 x 4 = 1498 N/ C how do i derive flux through each face?
