In estimating the capacitance of a given configuration of conductors, comparison with known capacitances is often . consider two configurations of conduc- tors in which the (n-1) conductors held at zero potential are the same, but the one conductor whose capacitance we wish to know is different. in particular, let the conductor in one configuration have a closed surface s, and in the other configu. ration have surface si, with si totally inside s. (a) use the extremum principle of section 1.12 and the variational principle of problem 1.17 to prove that the capacitance c' of the conductor with surface s is less than or equal to the capacitance c of the conductor with surface s, that encloses s. (b) set upper and lower limits for the capacitance of a conducting cube of side a. compare your limits and also their average with the numerical value, c -0.655(4 € 4).

Identify the correct relation showing that the radius r of the orbit of a moon of a given planet can be determined from the radius r of the planet, the acceleration of gravity at the surface of the planet, and the time τ required by the moon to complete one full revolution about the planet. determine the acceleration of gravity at the surface of the planet jupiter knowing that r = 71 492 km and that t= 3.551 days and r= 670.9 × 10^3 km for its moon europa.
