Compute all parts of given problem:
Problem: A cylindrical air capacitor with a length of 13.2m stores an amount of energy equal to 3.20×109J when the potential difference between the two conductors is 4.80V.
Part A: Calculate the magnitude of the charge on each conductor.
Q=________ C
Part B: Calculate the ratio of the radii of the inner and outer conductors.
r(in)/r(out) = _________
I need help to find the ratio of the radii of the inner and outer conductors.
