Question

Two point charges are located as shown in the picture. r_1 = 0.300 m, r_2 = 0.400 m, q_1 = + 5.00 mu C, q_2 = - 3.00 mu C a) What is the magnitude and direction of electric fields E^vector_1, and E^vector_2 of each charge at the origin O? b) Sketch the electric field vectors E^vector_1, and E^vector_2 at the origin on the picture. Make sure that both have proper directions. c) What is the magnitude and direction of the electric field E^vector of the whole system of charges at the origin? d) Sketch the total electric field vector E^vector at the origin on the picture. Explicitly show on picture the angle you found in (c). e) Suppose we place a third charge q_3 = -2.00 mu C at the origin O. What is the magnitude of the force acting on q_3 due to the total field E^vector of q_1 and q_2? What is the direction of this force? Show the direction explicity on the picture.
