       MCQ. 1-13 (odd)

Problems: 
1. C=Q/V = 3.6e-6
5.  Q_1 = Q_0 [C_1/(C_1+C_2)]
  Q_2 = Q_0 [C_2/(C_1+C_2)]
  V = Q_0 /(C_1+C_2)
6. C_2 = 87 microF
7.  1.2 C
10. C/l = 3.5e-11 F/m  or 35 pF/m
11. C=Q/(Q/4*pi*e0r) = 4*pi*e0 r = 7.10e-4 F
13. d = e0 A / C = 9e-16 m
16. Q_max = 2.2e-8 C
21. C_2 = 3.0e+3 pF
    Yes, a connection must be broken to add a capacitor
    in series.
22. a) C_eq = 19.2 microF
    b) C_eq = 0.53 microF
