Two in?nitely large sheets are shown in the ?gure. Sheet 1 contains a charge density +?. Sheet 2 contains ??. Between the two sheets is an in?nitely large 0.25 mm thick conducting plate that contains zero net charge. (a) What is the charge density induced on each side of the conducting plate. Explain. (b) What is the value of the electric ?eld at points A and B. Explain. (c) Calculate the voltage between the two sheets. Explain.

Expert Solution

Consider two parallel sheets of charge A and B with surface density of + and - respectively.

(a) The charge density induced on each side of a conducting plate which will be given as -

_A = Q_A / A (+q) / 4r²

_B = Q_B / A (-q) / 4r²

Then, we get

= _A + _B [(+q) / 4r²) + (-q) / 4r²]

= 0

(b) The value of an electric ?eld at points A and B which will be given as -

At points A, we have

E_A = _A / 2₀

E_A = + / 2 ₀

At points B, we have

E_B = _B / 2₀

E_B = - / 2₀

(c) The voltage between the two sheets which will be given by -

using a formula, we have

V_BA = E_BA . d

V = (E_B - E_A) d

V = [(- / 2₀) + ( / 2₀)] d

V = 0

Two very large parallel sheets are 5.00 cm apart. Sheet A carries a uniform surface charge density of -6.80 μC/m2 , and sheet B, which is to the right of A, carries a uniform charge density of -11.6 μC/m2 . Assume that the sheets are large enough to be treated as infinite. a) Find the magnitude of the net electric field these sheets produce at a point 4.00 cm to the right of sheet A. b) Find the direction of...

Given an infinite sheet of charge occupying the x-y plane such that the charge density is constant and uniform, find the electric field at any point on the z-axis by: A) Using the point charge formula for the electric field directly in cartesian coordinates. B) Using the point charge formula for the electric field directly in cylindrical coordinates. C) Using the point charge formula for potential in cylindrical coordinates and taking the gradient. DO NOT USE GAUSS'S LAW

Shown is a uniformly charged inner insulating sphere with radius a and with charge density given by ρ = ρ0(r3/a3). Outside of it is a conducting shell of inner radius b and outer radius c. This spherical shell also has double the charge of the inner non-conducting sphere. (So, if the inner sphere had charge “+Q”, the outer shell has charge “+2Q”.) The space between the sphere and the shell is empty. a) Describe/draw the charge distribution on the outer...
