An air capacitor consists of two parallel plates B as shown in the figure. Plate A is given a change and plate B is given a charge 3Q. P is the median plane of the capacitor. If `C_(0)` is the capacitor capacitor, then

`V_(P)-V_(A)=(Q)/(4C_(0))`

`V_(P)-V_(A)=(Q)/(2C_(0))`

`V_(P)-V_(A)=-(Q)/(C_(0))`

`V_(P)-V_(B)=-(Q)/(4C_(0))`
