Problem 4 [20 points] The gure below represents a set of equipotential surfaces in a region of space. Each equipotential is labeled by the value of the electrostatic potential in kilovolts (kV). (a) [ 5 points ] An electron is placed at point A and released from rest. Will electric forces move the particle to point B or to point D? Explain your reasoning (b) [ 10 points ] The electron from the previous part is shot at 105 m/s towards the opposite point you picked in the previous part (that is, if you picked B, it is shot towards D, and if you picked D, it is shot towards B). Will the electron make it there, or does it turn around at some point? Justify your answer with a calculation. (c) [ 5 points ] Draw the electric eld vectors at points A and B. Your drawing should show which of these electric eld vectors has the greater magnitude. Make sure to explain why you've drawn one vector larger than the other, or why they might be equal. Note: if you are drawing this on your own paper, you do not need to copy the entire diagram
