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'

Options

A. A point charge atpoint `P` will experience and electric force due to capacitor
B. The potential difference between the plates will be `3Q//2C`
C. The energy stored in the electric field in the region between the plates is `(9Q^(2))/(8C)`
D. The force on one plate due to the other plate is `(Q^(2))/(2pi epsilon_(0)d^(2))`

Answer

D
