In the figure shown the plates of a parallel plate capacitor have unequal charges. Its capacitance is 'C'. P is a point outside the capacitor and close to the plate of charge –Q. The distance between the plates is 'd'.
(A) A point charge at point 'P' will experience electric force due to capacitor
(B) The potential difference between the plates will be 3Q/8C
(C) The energy stored in the electric field in the region between the plates is Q2/2π ∈0d2
(D) The force on one plate due to the other plate is
