Two large, flat metal plates are parallel to each other, a distance d apart. A charge of Q is placed on them and then they are electrically isolated. As a result, at the midpoint between the two plates the electric field has magnitude E. If the separation of the plates is then reduced to d/2 what is the magnitude of the electric field at the midpoint?
A) 2E
B) E/2
C) 0
D) 4E
E) E
(1)(2)
I have taken:1)the surface area of the plate =A up
2)the dielectric constant of the medium=epsilon
To cover all the charges on the plate the maximum surface area it the Gaussian surface will be A.
