Particle A of charge 3.00 × 10 4 C is at the origin, particle B of charge 26.00 × 10 4 C is at (4.00 m, 0) and particle C of charge 1.00 × 10 4 C is at (0, 3.00 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.
