Question

Explain each step

14. S Review. Two identical particles, each having charge +q, are fixed in space and separated by a distance d. A third particle with charge -Q is free to move and lies initially at rest on the perpendicular bisector of the two fixed charges a distance xfrom the midpoint between those charges (Fig. P23.14). (a) Show that if x is small compared with d, the motion of -Q is simple harmonic along the perpendicular bisec- tor. (b) Determine the period of that motion. (c) How fast will the charge -Q be moving when it is at the midpoint between the two fixed charges if initially it is released at a distance a<< dfrom the midpoint? + q d 2 -Q +q Figure P23.14
