A)
since C1=C3 and C2=C4, due to symmetry
Q1=Q3 and Q2=Q4
Q1 = 21 microCoulomb
V3=V1=Q/C =21/8.5 = 2.47 V
this must be the voltage across 2 and 4 as well since 2 is in parallel to 1 and 4 is in parallel to 3
Q2 = V2*C2 = 2.47*17 =42 microCoulomb
Q4=Q1 by summetry
so, Q4 = 42 microCoulomb
Answer: 21,42,42
B)
As found above
Answer: 2.47,2.47,2.47,2.47 V
c)
Vba = 2.47 + 2.47 = 4.94 V
