http://www.kwantlen.bc.ca/science/physics/faculty/mcoombes/P2420_Solutions/VfromCharge/P2420_09_Solutions.htm does this explain what I'm trying to find, can anyone tell mehow they got dA?

is this the correct integral? basically integrating over the sphere times surface charge density and plugging that into the previous equation.

What I tried was up there, using gauss's law but it didn't quite work, then I tried integrating over the area of the shpere times the surface charge density and that didn't work. I don't think I'm setting this up right. Basically I need help solving for the dQ so that I can integrate.

I think that's the part I'm not getting how to do.

Homework Statement Okay I'm really scratching my brain out here, I've done this a thousand times but aparantly NOT the correct way, here's the problem A conducting spherical shell of radius R is charged uniformly with total charge Q. By DIRECT integration, find the potential at an...
