Q- Two positive, 1 nC charges are located on the x-axis. Charge Q1 is located at the origin and charge Q2 is located at (4,0) which is 4 cm from the origin.
(a) Calculate the magnitude and direction of the force experienced by Q2 due to Q1.
(b) A third charge Q3 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 Q2 due to both Q1 and Q3.
