Question

C1 S C2 СЗ S2 Three capacitors C-5 EC-8 F and C=10NF are connected as shown in Fig. Only capacitor C has initial charge of 80 C. Now, both switches are closed at the same time. What is the final charges stored in each capacitor? Yanitiniz: 1040 117 -UC 180 AQ,-14C, 22 - 3296, ;. 0 B) Q - 3 c., Q - 320 MC, Q.
