The Electric Field

9. a) Find the electric field at the point A (8,0) due to the charges Q1 (0,-6) = 2 μC and Q2 (0,6) = 2 μC and where the coordinates are measured in meters. b) What is the total force exerted by Q1 and Q2 on a charge Q3 = 6 μC located at A. c) Find the electric potential at A (8,0) and B (0,0). d) How much work is required to carry a 6 μC from A (8,0) to O (0,0). Answer: a) = A E r 216 i r N/C. b) ..... c) VA = 3600 V; VO = 6000 V. d) WA→O = 0.144 J
