1. The problem statement, all variables and given/known data For the curcuit shown in figure,which of the following statement is true? A)with S1 closed, V1=15V, V2=20V B)with S3 closed, V1=V2=25V C)with S1 and S2 closed, V1=V2=0 D)with S1 and S3 closed, V1=30V, V2=20V 2. Relevant equations ▪Q=CV, where Q and V are the charge and potential of a capacitor,C it's capacitance ▪Earthing a circuit means that potential at that point is zero. 3. The attempt at a solution I know how to do this kind of sums,writing potential 0 on one side,assuming V on the other side,assuming charges on the capacitor,using Q=CV.. BUT how do I find the polarity of the capacitors?? V1=30 could mean either the left or right plate is the negative one,I thought that if it isn't given in the question,maybe it won't matter,but it does (according to me,at least) Help appreciated..
