I just realized that I accidentally didn't post this in the homework help section...if any mods can move this, I'd appreciate it. Sorry for the trouble! Hello. I need help solving the following problem: Consider a spherical Gaussian surface and three charges: q1 = 1.60 μC, q2 = -2.26 μC, and q3 = 3.71 μC. Find the electric flux through the Gaussian surface if it completely encloses the following charges. (a) only charges q1 and q2 (b) only charges q2 and q3 (c) all three charges (d) Suppose a fourth charge, Q, is added to the situation described in part (c). Find the sign and magnitude of Q required to give zero electric flux through the surface. I'm pretty sure that this problem involves the equation φ = q/ε0, but have no idea on how to incorporate the given values into this problem. Any help would be greatly appreciated. Thanks in advance!
