Positive charge q is given to each plate of a parallel plate air capacitor having area of each plate A and seperation between them, d. Then find
(i) Capacitance of the system. (ii) Charges appearing on each surface of plates
(iii) Electric field between the plates (iv) Potential diffrence between the plates
(v) Energy stored between hte plates

Options

A. since both the plates are identically charged, therefore, capacitance becomes equal to zero
B. energy stored in the space between the capacitor plates is equal to `(q^(2))/(epsi_(0)A^(2))`.
C. no charge appears on inner surface of the plates
D. potential difference between the plates is equal to `(2qd)/(epsi_(0)A)`

Answer

C
