GO Figure 22-40 shows a proton (р) on the central axis through a disk with a uniform charge density due to excess electrons. The disk is seen from an edge-on view. Three of those electrons are shown: electron e c at the disk center and electrons e s at opposite sides of the disk, at radius R from the center. The proton is initially at distance z = R = 2.00 cm from the disk. At that location, what are the magnitudes of (a) the electric field E c → due to electron e c and (b) the net electric field E → s , net due to electrons e s ? The proton is then moved to z = R /10.0. What then are the magnitudes of (с) E c → and (d) E → s , net at the proton's location? (e) From (a) and (c) we see that as the proton gets nearer to the disk, the magnitude of E c → increases, as expected. Why does the magnitude of E → s , net from the two side electrons decrease, as we see from (b) and (d)? Figure 22-40 Problem 13.
