Q- Two positive, 1 nC charges are located on the x-axis. Charge Q_{1} is located at the origin and charge Q_{2} is located at (4,0) which is 4 cm from the origin.

(a) Calculate the magnitude and direction of the force experienced by Q_{2} due to Q_{1}.

(b) A third charge Q_{3} of 2 nC is positioned on the y-axis at (0,4) which is 4 cm from the origin. Calculate the magnitude and direction of the total force on Q_{2} due to both Q_{1} and Q_{3}.
