_Three Charges on Plane (Problem 17) Point charge A with a charge of +4.00 pC is located at the origin. Point charge B with a charge of +7.00 KC is located on the x axis at x = 7.00 cm. And point charge C with a charge of +3.00 uC is located on the y axis at y = 6.00 cm. . 1) What is the magnitude of the net force exerted on charge A by the others? (Express your answer to three significant figures.) . 2) What is the direction of the net force exerted on charge A by the others? (Express your answer as an @/ angle between 0 and 360 to four significant figures.) , measured counterclockwise from the +x direction
