Question: The sketch shows two identical capacitors, connected in series with a battery. The battery has an emf of E = 10 V. When connected as shown, the combination of capacitors carries a total of q = 6.0 × 10-6 C.

[A] Estimate the capacitance of the series combination of capacitors shown.
Cs = _____________ units

[B] Find øE – d A for the surface S1, shown in the sketch below. The surface encloses one plate of one of the capacitors. The answer can be left in terms of εor, but be sure to give the correct sign of the integral with your answer.
øE – d A = ____________unit.
[C] Estimate the capacitance of one of the capacitors.
C = ___________units
