Two parallel plates of equal area carry equal and opposite charges of magnitude

Two parallel plates of equal area carry equal and opposite charges of magnitude Q 0 . The potential difference between the two plates is V 0 . An uncharged conducting plate is slipped into the space between the plates without touching either one. The charge on the plates is adjusted to a new value Q 1 such that the potential difference between the plates remains the same.
1) Compare Q1 and Q0.A. Q1 < Q0.B. Q1 = Q0.C. Q1 > Q0.2) Compare the capacitance of the two configurations in the above problem.A. C1 > C0.B. C1 = C0.C. C1 < C0.
