Electric field of a charged plate...

None

A charged metal plate placed vertically has electric fields on either side as shown in figure:

10 V/m to the right and 8 V/m to the left.

So the charge density on the metal plate is:

1. 2

2. 4

3. 10

4. zero

[

=permittivity of the plate]

ps: I think the charge density should b zero, since a charged metal plate produces a uniform electric field..

in the entire region[

=charge density].

So in no way can the field b non uniform, lest there are some xternal charges.

Please post ur answers wid xplaination....

consider that this sheet is placed between two other plates with charge densities of +10 e on one side and -8e on the other, then on either side you may get electric fields equal to 10 V/m and 8 V/m.

In that case the net charge density of the block(Plate) will be 2e.
Here e stands for permeability.
