Two parallel plates, each of area 5.00 cm2, are separated by 2.00 mm with purified nonconducting water between them. A voltage of 7.00 V is applied between the plates. Calculate the following.
(a) the magnitude of the electric field between the plates
N/C
(b) the charge stored on each plate
nC
(c) the charge stored on each plate if the water is removed and replaced with air
nC
