Determine the values of a that provide half the maximum value of E#. let (b) be the lesser of the two values of a and (c) the greater of the two values

Two particles, each of positive charge g, are fixed in place on a y axis, one at y = d and the other at y = -d. Write an expression that gives the magnitude E of the net electric field at points on the x axis given by x = ad. Determine the value of a that gives (a) the maximum value of E. Determine the values of a that give half the maximum value of E.
