In Fig. 23-45, a small circular hole of radius R = 1.80 cm has een cut in the middle of an infinite, flat, nonconducting surface hat has uniform charge density o=4.50 pC/m². A z axis, with its rigin at the hole's center, is perpendicular to the surface. In unit- ector notation, what is the electric field at point P at z = 2.56 cm?

A conducting hollow sphere of internal radius a and external b has a total charge + 11q, determine the electric field between radius a and b in terms of ɛ0, q and the radius of the Gaussian r.

Figure (a) shows a nonconducting rod with a uniformly distributed charge +Q. The rod forms a 10/23 of circle with radius R and produces an electric field of magnitude Earc at its center of curvature P. If the arc is collapsed to a point at distance R from P (see Figure (b)), by what factor is the magnitude of the electric field at P multiplied? +Q +Q R (a) (b) Number i !

A non-uniform thin rod is bent into an arc of radius R. The linear charge density λ of the rod depends on θ and is given byλ= λ0/cos θwhere λ0 is a positive constant. The arc extends from θ = π/2 to θ = 3π/2  Sketch the direction of the resultant electric field at the origin.Calculate the magnitude of the electric field E⃗ .
