Practice Problem on Adding Capacitors
               C1=3 micro-F                      
          +--------||--------+           C4=6 micro-F
          |                  |      +--------||--------+
          |    C2=4 micro-F  |      |                  |
    ------+--------||--------+------+                  +------
          |                  |      |    C5=1 micro-F  |
          |    C3=2 micro-F  |      +--------||--------+
          +--------||--------+               
If the charge on C3 is 2 micro-C, what is the charge on C2? Give your answer to two decimal places.

ANSWER = 4.00 micro-C
