Two particles, each of positive charge q, 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 = αd. Determine the value of α that gives (a) the maximum value of E. Determine the values of α that give half the maximum value of E. Let (b) be the lesser of the two values of α, and (c) the greater of the two values.

Moon effect. some people believe that the moon controls their activities. if the moon moves from being directly on the opposite side of earth from you to being directly overhead, by what percentage does (a) the moon's gravitational pull on you increase and (b) your weight (as measured on a scale) decrease? assume that the earth–moon (center-to-center) distance is 3.82 × 10^8 m, earth's radius is 6.37 × 10^6 m, moon's mass is 7.36 × 10^22 kg, and earth's mass is 5.98 × 10^24 kg.
