Two plates, each of area 3.40*10-4 m2, are used to construct a parallel-plate capacitor with capacitance 1.20 pF.
(a) Find the necessary separation distance.
d = ?m

(b) If the positive plate is to hold a charge of 4.70* 10-12 C, find the charge density.
σ = ?C/m2

(c) Find the electric field between the plates.
E = ?N/C

(d) What voltage battery should be attached to the plate to obtain the preceding results?
V = ?V
