Two very large metal plates are separated by a distance 0.6 m and charged positive and negative as shown. A gun fires a proton through a hole in the negative plate, and we find that the proton barely reaches point A exactly halfway between the plates before it ィ4 stops and turns around. If the voltage difference between the plates is AValates 9000 V, find the charge density on the positive plate. 0.6 m А) 0.13 х 104 C/m? B) 0.67 x 10-7 C/m2 C) 4.31 x 10-5 C/m2 D) 1.33 x 10-7 C/m2 E) 9.85 x 103 C/m2 O A
