Eqdx=+FHGGIKJJ2102232πεαch. (b) The graph of E= Exversus is shown below. For the purposes of graphing, we set d= 1 m and q= 5.56 ×10–11C. (c) From the graph, we estimate Emaxoccurs at about = 0.71. More accurate computation shows that the maximum occurs at =12.(d) The graph suggests that“half-height” points occur at ≈0.2 and ≈2.0. Further numerical exploration leads to the values: = 0.2047 and = 1.9864. 84. Let q1denote the charge at y= dand q2denote the charge at y= –d. The individual magnitudes GE1and GE2are figured from Eq. 22-3, where the absolute value signs for qare unnecessary since these charges are both positive. The distance from
