Aring of charge, with charge Q and radiusR, is centered at the origin (x=0) and perpendicular to the x-axis. A point charge with charge q and mass m can slide along the x-axis.The point charges starts at the positionXi = 2R(it is twice the radius of the ring from the origin) and is given an initial velocity Vi to the right, away from the ring.How do I find the speed of the charge when it passes through the ring, at Xf=0Q = 40?Cq= -7?CR= 0.2 mm = 8.0 x 10?? kgVi = 53.3 m/S
