a distance x from the center of the ring (Q and q are different). The force exerted on the charge by the ring F= (1/4xe0) (gQx/ [(x² +a²)³²], where ɛo = 8.9 x 1012 C?/(N m²). Find the distance x where the force is 1.25 N if q and Q have the same value of 2 x 10³ C for a ring with a radius of0.85 m.given by
