RR

Question

The figure shows a proton (p) on the central axis through a disk with a uniform charge density due to excess electrons. Three of those electrons are shown: ec at the disk center and electrons es at opposite sides of the disk, at radius R = 1.49 cm from the center. The proton is initially at distance z = R = 1.49 cm from the disk. At that location, what are the magnitudes of (a) the electric field E→c due to the electron ec and (b) the net electric field E→s,net due to electrons es? The proton is then moved to z = R/10.0. What then are the magnitudes of (c)E→c and (d) E→s,net? Note that the magnitude of E→c increases while the magnitude of E→s,net decreases.
