Question

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 x from the midpoint between those charges (see figure below). tq -Q a) Show that if х ıs small compared with d, the motion of Q is simple harmonic along the perpendicu arbi sector. Submit a e h a maximum size of E Choose File No file chosen This answer has not been graded yet. (b) Determine the period of that motion. (Use the following as necessary: q, Q, m for the mass of charge Q, d, and ke.) (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 <<d from the midpoint? (Use the following as necessary: a, q, Q, m for the mass of charge Q, d, and ke.)
