A ring of charge, with charge Q and radius R, 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 position 131- = 2R (it is twice the radius of the ring from the origin) and is given an initial velocity 3,- to the right, away from the ring. What is the speed of the charge when it passes through the ring, at mf = 0. Q = 30.5 #0, q = - 9.71 #0, R = 0.18 m, m = 7.07 x 10'4 kg, vi = 36.7 m/s Give your answer in Newtons to at least three digits to avoid being counted off due to rounding. A ring of charge, with charge Q and radius R, is centered at the origin (x=0) and perpendicular to the x-axis. A point charge with charge q can slide along the x-axis. What is the magnitude of the force on the point charge due to the ring if the charge is at x = 2R? (The point charge is a distance twice the ring's radius from the center of the ring.) Q = 56.4 [1,0, q = - 4.84 [1,0, R = 0.21 m Give your answer in Newtons to at least three digits to avoid being counted off due to rounding
