A parallel-plate capacitor is connected to a cell. Its positive plate `A` and its negative plate `B` have charges `+Q` and `-Q` respectively. A third plate `C`, identical to `A` and `B`, with charge `+Q`, is now introduced midway between `A` and `B`, parallel to them. Which of the following are correct?

A

The charge on the inner face of B is now `-(3Q)/(2)`

B

There is no change in the potential difference between A and B

C

The potential difference between A and C is one-third of the potential difference between B and C

D

The charge on the inner face to A is now Q/2
