Question

An infinite sheet of charge, oriented perpendicular to the x-axis, passes through x = 0. It has a surface charge density ?1 = -2.1 ?C/m2. A thick, infinite conducting slab, also oriented perpendicular to the x-axis occupiees the region between a = 2 cm and b = 4.2 cm. The conducting slab has a net charge per unit area of ?2 = 73 ?C/m2.

1)

What is Ex(P), the value of the x-component of the electric field at point P, located a distance 7.7 cm from the infinite sheet of charge?

2)

What is Ey(P), the value of the y-component of the electric field at point P, located a distance 7.7 cm from the infinite sheet of charge?

3)

What is Ex(R), the value of the x-component of the electric field at point R, located a distance 1 cm from the infinite sheet of charge?

4)

What is Ey(R), the value of the y-component of the electric field at point R, located a distance 1 cm from the infinite sheet of charge?

5)

What is ?b, the charge per unit area on thesurface of the slab located at x = 4.2 cm?

6)

What is Ex, the value of the x-component of the electric field at a point on the x-axis located at x = 2.88 cm ?

7)

What is ?a, the charge per unit area on the surface of the slab located at x = 2 cm?

8)

Where along the x-axis is the magnitude of the electric field equal to zero?
