The figure below shows a ring of outer radius R = 13.0 cm, inner radius r = 0.480R, and uniform surface charge density σ = 6.20 pC/m2. With V = 0 at infinity, find the electric potential at point P on the central axis of the ring, at distance z = 3.20R from the center of the ring. V
The figure shows a ring of outer radius R = 23.0 cm, inner radius r = 0.160R, and uniform surface charge density σ = 8.00 pC/m2. With V = 0 at infinity, find the electric potential at point P on the central axis of the ring, at distance z = 2.10R from the center of the ring.
need help with this question please FR2 R1 х A flat ring of inner radius R, and outer radius Ry has a uniform surface charge density of o. Find an expression for the electric field for points along the x-axis in two ways: (a) Calculate the potential first by treating the ring as a continuous charge distribution. Then find the electric field from the potential. (b) Calculate the electric field directly by treating the ring as a continuous charge distribution.
Consider a charged ring with radius R and uniform line charge density +λ.(a) Find the electric field at the center O of the ring. (b) What is the electric field at a field point P which is on the central axis with a distance z above the center? (c) Show that in the limit when z » R, the electric field reduces to the form Does this result physically make sense? Explain. (d) Using binomial approximation, , find the electric field at points along the...
Suppose you design an apparatus in which a uniformly charged disk of radius R is to produce an electric field. The field magnitude is most important along the central perpendicular axis of the disk, at a point P at distance 4.50R from the disk (see Figure (a)). Cost analysis suggests that you switch to a ring of the same outer radius R but with inner radius R/4.50 (see Figure (b)). Assume that the ring will have the same surface charge...

1. A very long, uniformly charged cylinder has radius R and charge density \rho. Determine the electric field of this cylinder inside (r<R) and outside (r>R)2. A large, flat, nonconducting surface carries a uniform surface charge density σ. A small circular hole of radius R has been cut in the middle of the sheet. Determine the electric field at a distance z directly above the center of the hole.3. You have a solid, nonconducting sphere that is inside of, and...
