Particle A of charge 5.00x10-4 C is at the origin, particle B of charge -5.00x10-4 C is at (3.00 m, 0) and particle C of charge 3.00x10-4 C is at (0, 2.00 m).(a) What is the x-component of the electric force exerted by A on C?
(b) What is the y-component of the force exerted by A on C?
(c) Find the magnitude of the force exerted by B on C.
(d) Calculate the x-component of the force exerted by B on C.
(e) Calculate the y-component of the force exerted by B on C.
(f) Sum the two x-components to obtain the resultant x-component of the electric force acting on C.
(g) Repeat part (f) for the y-component.
(h) Find the magnitude and direction of the resultant electric force acting on C.
