Question

Two vertical infinite charged sheets are parallel to each other
and separated by 0.500 meters. The sheet on the left has a surface
charge density of sigma= +10.0 microC/m^2, while the sheet on the
right has a surface charge density of sigma = -5.00
microC/m^2.

a) What is the magnitude and direction of the electric field
between the plates?

b.) What is the magnitude and direction of the electric field in
the region that is to the left of both plates?

Two infinite, nonconducting sheets of charge are parallel to
each other as shown in the figure below. The sheet on the left has
a uniform surface charge density σ, and the one on the
right has a uniform charge density −σ. Calculate the
electric field at the following points. (Use any variable or symbol
stated above along with the following as necessary:
ε0.)

Three parallel sheets of charge, large enough to be treated as
infinite sheets, are perpendicular to the x-axis. Sheet A has
surface charge density σA = +8.00 nC/m2. Sheet B is 4.00 cm to the
right of sheet A and has surface charge density σBσB = -4.00 nC/m2
Sheet C is 4.00 cm to the right of sheet B, so is 8.00 cm to the
right of sheet A, and has surface charge density σC = +6.00
nC/m2

Three parallel, “infinite” sheets of charges are
horizontal,
parallel to the x-y plane. The sheet at z = -5 m is charged at
-2
μC/m2. The sheet at z = 0 is charged at 9 μC/m2. The sheet at z
=
5 cm is charged by -15 μC/m2. Find the magnitude and direction
of
the electric field at a point P with Cartesian coordinates (2
m,
-3 m, 6 m).

a. Consider two infinite sheets parallel to the xy
plane, separated by distance d, carrying charge densities
+? and -?. Solve for and sketch the potential as
a function of z.
b. Consider two disks of radius R parallel to the
xy plane, centered on the z axis and separated by
distance d, carrying charge densities +? and
-?. (In a real capacitor, the charge density will not be
strictly uniform, but we will continue to ignore that for the...

oppositlely charged parallel plates are separated by
5.00 mm. A potential difference of 400.0 v exists between the
plates. a) what is the magnitude of the electric field between the
plates? b) how much work does the electric field do moving an
electron from the negative plate to the positive plate?

We have an infinite sheet that is vertical. Instead of having a
uniform charge density, it has a uniform current density, which is
the current per unit length carried by the sheet (and has units of
Amperes per meter). For reference,let z be vertical, and y be
horizontal, so that x is coming out of the page. That means the
sheet occupies the entire xz-plane, and positive y-values are to
the right of the sheet.Let the current density point in...
