A circular ring of radius "a" has a total charge Q uniformly distributed along the top half (Q is distributed along the semicircle in quadrants I and II) What is the potential at a point located on the bottom of the ring (observation point is on the ring in quadrant III or IV). The location of the observation point is described as being located at an angle psi measured from the positive x axis. You want V(a, psi).
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) Consider a uniformly charged, thin-walled, right circular cylindrical shell having total charge Q, radius R, and length l. Determine the electric field at a point a distance d from the right side of the cylinder as shown in Figure P23.46. Suggestion: Use the result of Example 23.8 and treat the cylinder as a collection of ring charges, (b) What If? Consider now a solid cylinder with the same dimensions and carrying the same charge, uniformly distributed through its volume....
A ring with radius R and a uniformly distributed total charge Q lies in the xy plane, centered at the origin. (Figure 1) Part B What is the magnitude of the electric field E on the z axis as a function of z, for z >0?
A charge Q is distributed uniformly around the perimeter of a ring of radius R. Determine the electric potential difference between the point at the center of the ring and a point on its axis at a distance 11R from the center. (Use any variable or symbol stated above along with the following as necessary: ke.) ΔV = V(0) − V(11R) =
A charge Q is distributed uniformly around the perimeter of a ring of radius R. Determine the electric potential difference between the point at the center of the ring and a point on its axis at a distance 20R from the center.
MI.1. A thin circular plastic ring carries a net charge that is uniformly distributed throughout the ring with a linear density of λ = 3.4 × 10-6 C/m. This ring is positioned parallel to a neutrally- charged infinite conducting plane such that its distance from the plane equals the radius (a) of the ring Fig.1]. It can be shown that the magnitude of the electric field on the axis of the this ring is given by: 20 (a+r2)3/2 where x...
Ring of Charge A uniform circular ring of charge Q =-5.70 μ C and radius R = 1.28 cm is located in the x-y plane, centered on the origin as shown in the figure Part A What is the magnitude of the electric field, E at the origin? 0.000 N/c The direction of the electric field, E at the origin?

Consider a uniformly charged, thin-walled, right circular cylindrical shell having total charge Q, radius R, and length l. Determine the electric field at a point a distance d from the right side of the cylinder as shown in the figure. Show that you recover the same expression if the cylinder is treated as a collection of ring charges. Consider now a solid cylinder with the same dimensions and carrying the same charge, uniformly distributed through its volume. Find the field...
