There is a charge A of -8.4 µC at x = 4 cm and y = 8 cm. There is a charge B of -8.9 µC at x = 10 cm and y = -6 cm. A) What is the magnitude of the force (in Newtons) of A on B? B) Is the direction of the force on A towards B or away from B? C) What is the magnitude of the electric field at x = 0 cm and y = 0 cm?
