Solve part c of the image, include all the procedures to arrive at the result.

What If? After a very long time, switch S1 is also closed. By what amount does the charge on the second capacitor change after S1 has been closed for a very long time? (Give your answer in µC.)

Consider the circuit shown in the figure below, where C, = 8.00 µF, C, = 6.00 µF, and AV = 18.0 v. Capacitor c, is first charged by closing
switch S,. Switch s, is then opened, and the charged capacitor is connected to the uncharged capacitor by closing S,.
AV
S2
(a) Calculate the initial charge (in µC) acquired by C,. (Round your answer to at least one decimal place.)
144
V µC
(b) Calculate the final charge (in µC) on each capacitor. (Round your answers to at least the nearest integer.)
