A capacitor,consisting of two metal plates each of area 50cm2 and space 0.2mm apart in air ,is connected across a 120V supply.Calculate (1)the energy stored..(2)the electric flux density and the potential gradient..

Answer 1

Q = CV
and C = epsilon A/d
You'll have to look up the permittivity of free space number.
Oops. You wanted energy stored. That's 1/2CV^2.
And density is 1/2 epsilon E^2
