Find the net electric flux through the spherical closed surface shown in the figure below. The two charges on the right are inside the spherical surface. (Take q1 = +1.84 nC, q2 = +1.02 nC, and q3 = 2.91 nC.)

Best ResponseYou've already chosen the best response.0By Gauss' theorem, the flux through a Gaussian surface is equal to the sum of the charges inside the surface scaled by 1/4.pi.e0. use that result.

Best ResponseYou've already chosen the best response.0they're the only charges in the surface, yes. I strongly recommend you watch the lecture I just linked in your other question.

Best ResponseYou've already chosen the best response.0**correction: no 4.pi. That goes away in the integration.

Best ResponseYou've already chosen the best response.0You know you're in danger in Physics when you're using equations and you don't know where they come from. Use that rule to be intellectually honest with yourself: what is this equation, where did come from, what does it mean physically, can I derive it from first principles in physics?

Best ResponseYou've already chosen the best response.0hmm... so I'm getting ((1.02x10^9)(2.91x10^9)/8.85x10^12=2.14x10^20 ?? that doesn't seem right
