We have three isolated spherical shells on which we put positive charges. For each shell, this next figure shows?

We have three isolated spherical shells on which we put positive charges. For each shell, this next figure shows the electric potential V at radial distances r starting at the center point.

Q1:

Rank the shells according to their radii R .Indicate the ranking with the greatest Use arrange in numeric order.

Q2:

Now rank the shells according to their charge. Indicate the ranking by moving the labels into the boxes, with the greatest charge at the top left. Use side-by-side boxes for any ties, arrange in numeric order.

    Clearly shell 1 has the largest radius and shell 3 has the smallest. The potential is constant within the shell -- that is, for r < R_shell.

    Shell 1 has the largest radius and also the largest potential (from the graph). Since

    potential = k * Q/r,

    it must also have the largest charge. Shell 3 must have the smallest charge.
