22M.2.HL.TZ1.a

Two capacitors C1 and C2 of capacitance 28 µF and 22 µF respectively are connected in a circuit with a two-way switch and a cell of emf 1.5 V with a negligible internal resistance. The capacitors are initially uncharged. The switch is then connected to position A.

Show that the charge stored on C1 is about 0.04 mC.
