3.12 An infinite, thin, plane sheet of conducting material has a circular hole of radius a cut in it. A thin, flat disc of the same material and slightly smaller radius lies in the plane, filling the hole, but separated from the sheet by a very narrow insulating ring. The disc is maintained at a fixed potential V, while the infinite sheet is kept at zero potential. (a) Using appropriate cylindrical coordinates, find an integral expression involv- ing Bessei functions...
1.) We consider a thin metal strip with conductivity o and thickness d oriented in the (x,y)-plane and moving at constant velocity v = vj in the y-direction, as shown. The metal strip falls in the air gap between the rectangular pieces of an electromagnet. The cross-sectional with of each pole is w along the r-direction) and length 1 (along the vertical). The electromagnet produces the magnetic field B = Bk (out-of-the-page). We treat this problem approximately by considering the...
A sheet of metal coincides with the square in the xy-plane whose vertices (0, O), (1 0), (1, 1) and (0, 1). The two faces of the sheet are insulated, and the sheet is so thin that heat flow in it can be regarded as two-dimensional. The edges parallel to the x- axis are insulated, and the left-hand edge is maintained at the constant temperature O. If the temperature distribution u(1, y) f(y) is maintained along the right-hand edge, Set...
problem 40 with parts
40. The atmospheric pressure (force per unit area) on a surface at an altitude z is due to the weight of the column of air situated above the surface. Therefore, the difference in air pressure p between the top and bottom of a cylindrical volume element of height Az and cross-section area A equals the weight of the air enclosed (density ρ times volume V-: ΑΔε times gravity g), per unit area: Let Δ、→0 to derive...

x=L The rail gun consists of two thick conducting rails connected to a power supply and there is a magnetic field assumed to be uniform and constant in the direction shown. A short conducting bar that is to be (or carry) the projectile is placed across the bars at x -0. The current flows through the bars as shown. The magnetic force on the bar causes it...

Problem 4 (20 points): An infinite sheet of charge (i.e. infinite in the y- and z- directions) with thickness 2d lies in the 12-plane between x =-d and x = +d. An edge view (ie, cross-section) of this thick, planar sheet of charge is shown in the figure. This particular insulating sheet has a non-uniform volume charge density p (C/m') that varies as a function ofx, given by p(x)-Pn(x1), where Pols a positive constant. a) Can Gauss's Law be used...
