A charged metal sphere of radius RS and a charged, at metal disk of radius RD are connected by a long conducting wire. The sphere has a charge Q5 (assume it is uniformly distributed on its surface). What is QD, the charge on the disk (assume it is uniformly distributed on its surface)? Give your answer in nC to at least three digits to avoid being counted off due to rounding. R5 = 0.55 m, RD = 0.37 m, QS = 36.3 nC
