A parallel plate capcitor of capacitance `C` is having charge `q_(0)` on each plate. Now it is connected to a battery of emf `V`.
(A) The battery supplies charges `+CV` and `-CV` to two plates
(B) The outer surface of the plates have equal charges `q_(0)`
(c) The facing surface have equal and opposite charges of magnitude `CV`

Options

A. `A,B`
B. `A,C`
C. `B,C`
D. A,B,C`

Answer

D

Explanation

When battery is connected to a capacitor, it supplies equal and opposite charged to two plates, `(A)` is O.K.
The outer surface have charges `((Q_(0)+CV)+(q_(0)-CV))/(2)=q_(0)`, `(B)` is O.K.
Charge distribution
`(c)` is O.K.
