58. (a) In the process described in the problem, no charge is gained or lost. Thus, q = constant. Hence, q = C 1 V 1 = C 2 V 2 = V 2 = V 1 C 1 C 2 = (200) µ 150 10 = 3000 V . (b) Eq. 28-36, with τ = RC , describes not only the discharging of q but also of V .Thu s , V = V 0 e t/τ = t = RC ln µ V 0 V = ( 300 × 10 9 )( 10 × 10 12 F ) ln µ 3000 100 which yields
