Hello guys, well its that time of the week when I am busy working on my homework again!
One of this weeks questions is that there are 2 hollow concentric conducting spheres which hold charges Q1 (inner shell, radius R1), and Q2 (outer shell, Radius R2 )
1) Find the potential difference between them. I think this is (Q2-Q1)/4*Pi*E0*r ?
2)If q1 is +ive, and a wire connection is made from inner to outer conductor, charge will flow. How does direction of flow depend upon the magnitude and sign of Q2?
I think charge will flow from higher to lower potential, ie if Q2 is a smaller +ive charge, charge will flow from q1 to q2.
Is negative charge a lower potential than a positive, I guess?
But this next part really gets me: What is the capacity of the above pair of conductors? (Answer 4*Pi*E0*R1R2/(R2-R1) )
What on Earth does "capacity" mean, we haven't come across that term before! I would appreciate a poke in the right direction for this! There is another part but I haven't tried that yet so I won't post here.
Any help and hints (but no solutions please it is assesed) are most appreciated :-)
Thank you
