The electric field on the axis of a ring of charge near its center( which is located at z=0) is given by E(z)= ((kQ)/(R^3)) z. The ring has a radius R=5 and total charge of Q= 1 uC 1. A charged particle (m = 1 mg, q = –1 nC) is placed near the center of the ring. Write down and expression for the force F(z) that acts on the particle, in terms of kC, Q, q, R and z....

A thin nonconducting rod with a uniform distribution of positive charge Q is bent into a circle of radius R (see the figure). The central perpendicular axis through the ring is a z axis, with the origin at the center of the ring. What is the magnitude of the electric field due to the rod at (a) z = 0 and (b) z = ∞?

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...

Find an expression for the position y (along the positive axis perpendicular to the ring and passing through its center) where the electric field due to a charged ring is a maximum. Also find an expression for the electric field at that point. (Use the following as necessary: R for the radius of the ring, Q for the charge on the ring and k for Coulomb's constant. Enter the magnitudes. Assume Q is positive.) y = E =
