A hole of radius R1 = 0.5 m is drilled alongthe symmetry axis of an infinite, non-conducting solid cylinder ofradius R2 = 2.3 m. The resulting annularcylinder is given a uniform volume charge density r = +1.25 µC/m3.
(a) Calculate the magnitude of the electric fieldE at the following values of r, wherer is the radial distance measured perpendicularly from theaxis of symmetry (z-axis).
At r = 0.25 m: E = N/C *
At r = 0.75 m: E = N/C
At r = 4.6 m: E = N/C
