Unformatted text preview: radius b. The shell has a total charge q. What is the magnitude of the electric field at radial distances; (a) r < a, (b) a < r < b, (c) r > b ? + q a b Q5: A non uniform but spherically symmetric distribution of charge has a charge density given by the relation, R r 1 for r R =0 for r R where 3 R Q 3 is a constant a) Show that the total charge contained in the charge distribution is Q . b) Show that for the region r R the electrical field is identical to that produced by a point charge Q . c) Obtain an expression for the electric field in the region r R. Q6 : In figure, an electron of mass is released between two infinite nonconducting sheets that are horizontal and have uniform charge densities . What is the magnitude and direction of the acceleration of the electron?...
