The electric field has been measured to be horizontal and to the right everywhere on the closed box as shown in the figure below. All over the left side of the box Ej = 107 V/m, and all over the right (slanting) side of the box E2 = 358 V/m. On the top the average field is E3 = 160 V/m,on the front and back the average field is E4 = 180 V/m, and on the bottom the average field is E5 = 200 V/m.

Class: Electromagnetics Consider a fixed hollow spherical shell with radius R and surface charge +? (sigma). A particle with mass m and charge -Q that is initially at rest falls in from infinity. Assume that a tiny hole has been cut in the shell to let the charge through. Determine the speed of the particle when it reaches the center of the shell. Your answer should be a function of ? (sigma), Q, and m.

Subject: Electromagnetics A ring with radius r has charge -Q uniformly distributed around it. The ring is located a distance h from an infinite grounded conducting plane. Let z be the vertical coordinate with z = 0 taken to be the center of the infinite conducting plane.a. Find the electric field above the conducting plane and the induced surface charge density on the plate. Your answers should be a function of Q, r, and h.b. If the ring is released from rest at a distance h from the infinite grounded conducting plane, determine the speed of the ring when it is located h/10 from the infinite grounded conducting plane.
can you tell me what is wave propagation and how it relates to Bessel? you don't have to go in-depth. I just want to know how Bessel's differential equation helps with wave propagation.
