A Total Charge Q Is Uniformly Distributed Around A Ringshaped

A total charge Q is uniformly distributed around a ring-shaped conductor with radius α. A charge q is located at a distance x from the center of the ring (Figure). The force exerted on the charge by the ring is given by

Where e0 = 8.85 x 10–12 C2/(N m2). Find the distance x where the force is 1.25 N if q and Q are 2 x 10–5 C for a ring with a radius of 0.9 m.
