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.

Consider two oppositely charged, isolated parallel plates separated by distance D, with capacitance C, charge Q, and stored energy U. D is small compared to the dimensions of the plates. For each statement below, select "True" or "False". 1. Because of energy conservation, inserting a dielectric leaves U unchanged. 2. When D is halved, Q stays the same. 3. Inserting a dielectric decreases C. 4. When D is doubled, U increases. 5. When D is doubled, C is doubled. 6....

Two thin square flat sheets are placed parallel to each other. The distance between the sheets...

Two thin square flat sheets are placed parallel to each other. The distance between the sheets is much smaller than the size of each sheet, so we can consider the sheets infinite. The sheets are uniformly charged, with surface charge densities σ1 and σ2, respectively. The magnitudes and the signs of these charge densities are not known. To determine σ1 and σ2, you measure the electric force on a test point charge q = 2.00 nC at several locations. You...

Two large parallel copper plates are 3.60 cm apart and have a uniform electric field of magnitude E = 7.98 N/C between them (see the figure).

Neglect the force of the particles on each other and find their distance from the positive plate when they pass each other.

Consider the steady flow between two flat plates. The plates are 10 cm apart and the width of the channel is 10 cm. Water is the working fluid. The flow velocity varies linearly from zero at the bottom plate to 10 m/s at the top plate. (This general class of flows is known as Couette Flow). Determine the total mass flow and momentum per unit time crossing an imaginary plane across the channel.

Consider two-dimensional incompressible plane viscous flow between parallel plates a distance 2h apart, with the origin along the centerline. The plates are very wide and very long, so that the flow is essentially axial. The present case is where the upper plate moves at velocity V but there is no pressure gradient. Neglect gravity effects. Determine the velocity profile for this flow.
