Two flat 4.0 cm × 4.0 cm electrodes carrying equal but opposite charges are spaced 2.0 mm apart with their midpoints opposite each other. between the electrodes but not near their edges, the electric field strength is 6.8 × 106 n/c. what is the magnitude of the charge on each electrode? (ε 0 = 8.85 × 10-12 c2/n · m2)

Explanation:

The electric field between two charged plates is uniform, and its strength is given by

where

is the charge density, with Q being the charge on one plate and A the area of the plate

is the dielectric constant

Since we know the magnitude of the field, , we can find the charge density:

The area of each plate is

So the charge on each electrode is

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
