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

Answer

`(i) C=(epsilon_(0)A)/(d)`
(ii) on outer surfaces charge=q
on inner surfaces charge=0
`(iii) E=0 " " (iv) DeltaV=0 " " (v)U=0`
