[cnh1995]

You have used incorrect formula for voltage across capacitor.

You need to write the voltage across capacitor in terms of charge and capacitance.

 

[Kelsi_Jade]

Should be V=Q/C?

 

[cnh1995]

Should be V=Q/C?

Yes.

 

[Kelsi_Jade]

So, would this be accurate?

I think that's right for (a). Much better than before.

For (b) you don't actually need the answer to (a). You might be able to say it off back of head.

After which calculation of (a) is a bit simpler.

Here Matrices and determiants is how you can make pages like yours look better.
