For example, on this website http://www.chemguide.co.uk/physical/redoxeqia/combinations.html in the second diagram from the top, it shows that *if a high resistance voltmeter is placed between two pieces of metal, zinc and copper, the zinc metal will accumulate a build up of electrons.* Then...

Thank you! I finally noticed that after way too long...

Okay, thank you for helping. I just realized the gap in my logic which would be too confusing to explain...

Thanks. I understood that the field at points on the Gaussian surface is zero, but I don't understand where the -q1 comes from. The net charge on the exterior surface of the shell is +q2, and the net charge on the solid sphere is +q1. But why is it that at a point A between the inner shell...

Why do I have to integrate? Isn't it redundant? Homework Statement The volume charge density inside a solid sphere of radius a is given by ρ=ρnaught*r/a, where ρnaught is a constant. Find the total charge as a function of distance r from the center. Homework Equations Q=ρV The...

Why is the Qenclosed zero if there's a charge inside the shell? Homework Statement A solid conducting sphere of radius a is placed inside a conducting shell which has an inner radius b and an outer radius c. There is a charge q1 on the sphere and a charge q2 on the shell. Find the...
