For a system of charges shown in Figure find al electric field vector ( magnitude and direction) at point ( (20pts) potential difference between points C'and B (15pts). Il a proton is placed at point B and released with initial velocity =1x10 m/s along positive I-axis it will move away from the system of charges to infinity. What is the proton's speed at infinity ? (Topts) (Note: the proton mass: mo-1.67x10 -kg; the proton charge qp=1.6x10-19 C 2 m 4m
