Figure 22-40 shows a proton (p) 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 oppo- site 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 E⃗_c due to electron e_c and (b) the net electric field E⃗_s net due to electrons e_s ? The proton is then moved to z=R / 10.0 . What then are the magnitudes of (c) E⃗_c and (d) E⃗_ snet at the proton #x27;s location? (e) From (a) and (c) we see that as the proton gets nearer to the disk, the magnitude of E⃗_c increases, as expected. Why does the magnitude of E_s, n net from the two side electrons decrease, as we see from (b) and (d)?
