Finding the ratio of the inner and outer radii

  • #1
I'm not sure how to use the formula in this problem (C/L = (2*pi*E_0)/(In(r_b/r/a)), A cylindrical air capacitor with a length of L stores an amount of energy equal to W when the potential difference between the two conductors is V. So the magnitude of the charge on each conductor would be 2W/V, now how do you calculate the radii of the inner and outer conductors?

Is there is any other formula for energy involving capacitance C and potential difference V.
