Suppose you have a sphere (sphere A) with net positive charge 2Q. A conducting spherical shell (sphere B) of inner radius b and outer radius c is concentric with the solid sphere and carries a net charge -Q.
When you calculate the flux between both spheres (gaussian surface with radius between both of the spheres), you're suppose to only add up the charges INSIDE the gaussian surface--that is just sphere A.
I understand that this is because of the formula which has ##q_{enclosed}/\epsilon_0## , but don't get this visually. Ill rephrase it: Why does the outer charge (sphere B) have no effect on the flux of the surface that we created? Doesn't the electric field have a relation to the flux? [tex]\int \vec{E}\vec{dA} = \Phi [/tex] ?

P.S. why doesn't # work for latex?
EDIT: i realized this is in the wrong forum, can a mod please move this
