Charge q1 = 6.01·10-8 C is placed at the origin. Charges q2 = -1.33·10-8 C and q3 = 1.75·10-8 C are placed at points (0.185 m,0 m) and (0 m,0.211 m), respectively, as shown in the figure.
a) Determine the magnitude of the net electrostatic force on charge q3.
b) Determine the direction of the net electrostatic force on charge q3 (angle with respect to the positive x-axis).
