Electric Field from Charge Distributions 1. A thin ring of radius a is uniformly charged with total charge Q. A. Find an expression for an electric field at a point, x, along the axis perpendicular to the ring. B. Verify that the limit x >>a gives the expected result. C. Sketch a graph of E vs x. Where is the electric field a maximum? dg dE IE

For the next six problems, consider a uniformly charged disk of radius R. The total charge on the disk is Q. To find the electric potential and field at a point P (x>0) on the x-axis which is perpendicular to the disk with the origin at the center of the disk, it is necessary to consider the contribution from an infinitesimally thin ring of radius a and width da on the disk, as shown. What is the surface charge density...

A uniformly charged disk of radius 25.0 cm carries a charge density of 6.50 x 10-3 C/m2. a) from the definition of the electric field, derive the expression of the net electric field along the perpendicular line going through the center of the disk. b) calculate the electric field on the axis of the disc at 50 cm from the center of the disk. c) calculate the electric field on the axis of the disc at 2 m from the...

The electric field along the axis of a uniformly charged disk of radius R and total charge Q is given below. Ex = 2πkeσ 1 − x (x2 + R2)1/2 Show that the electric field at distances x that are large compared with R approaches that of a particle with charge Q = σπR2. Suggestion: First show that x (x2 + R2)1/2 = 1 + R2 x2 −1/2 , and use the binomial expansion (1 + δ)n ≈ 1 +...

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 2.50R from the disk (Fig. a).
Cost analysis suggests that you switch to a ring of the same outer
radius R but with inner radius R/2.00 (Fig. b). Assume that the
ring will have the same surface charge density as...

Figure (a) shows a circular disk that is uniformly
charged. The central z axis is perpendicular to the disk
face, with the origin at the disk. Figure (b) gives the
magnitude of the electric field along that axis in terms of the
maximum magnitude Em at the disk surface. The
z axis scale is set by zs = 41.0 cm.
What is the radius of the disk?

Uniformly Charged Disk Part A The figure below shows a thin uniformly charged disk with surface charge density σ and radius R. Imagine the disk divided into rings of varying radii r. Find an expression for the charge dą on a ring with radius r and thickness dr. Your expression should be in terms of the given variables and other known constants such as k Greek letters should be spelled out, for example type sigma" without the quotations for σ...
