An extremely large disk has a radius of 10 meters. A total charge of +4 micro coulombs has been distributed evenly over the surface of the disk. A small charged particle of mass 0.25 kilogram and charge +3.2 x 10-19 coulombs is released from rest at the center of the disk, very near the surface of the disk. How fast is the particle moving when it has traveled a distance of 0.11 meters?

A square with sides of length 0.4 meters has 8 charges on it. Four charge of +q, +q, +q, and -q (same amount of charge for three and one has an opposite sign) are placed in the corners and four charges of twice the magnitude of -2q, -2q, -2q, and +2q are placed halfway in the middle of the sides. Here q = 9 micro-coulombs. (In other words, -q = -9 micro-coulombs and +2q is twice 9 micro-coulombs.) A ninth...

A circular plastic disk with radius R = 3.33 cm has a uniformly distributed charge Q = +(5.81 x106)e on one face. A circular ring of width 30.6 µm is centered on that face, with the center of that width at radius r = 0.687 cm. In coulombs, what charge is contained within the width of the ring?
A circular plastic disk with radius R = 3.35 cm has a uniformly distributed charge Q = +(1.81 x106)e on one face. A circular ring of width 38.0 µm is centered on that face, with the center of that width at radius r = 0.447 cm. In coulombs, what charge is contained within the width of the ring?
A thin disk with a circular hole at its center, called an
annulus, has inner radius R1 and outer radius R2. The disk has a
uniform positive surface charge density σ on its surface. (Figure
1)
A)The annulus lies in the yz-plane, with its center at
the origin. For an arbitrary point on the x-axis (the axis
of the annulus), find the magnitude of the electric field E⃗ .
Consider points above the annulus in the figure.
