Ok guys, these are just questions from our book(like critical thinking type).....she said to be able to understand these, for the upcoming test. I'm not sure I fully understand them(if at all). 1. If a closed surface surrounds a dipole, the net flux through the surface is zero. True or False? 2. If the net flux through a closed surface is zero, then there can be no charge or charges within that surface. True or False? I think the equation to find flux is Gauss's Law, which says E=Q(enclosed)/E(knot). With Q being a negative number(dipole), then I'd say the flux can't be zero. Along with what I just said, then if Q=0, then there can not be any flux within that surface.....right? Thanks guys!!! Brad Oh, one more question. Are Equipotential lines vectors? I'm thinking they are, but need to know to figure a question.
