Problem 5: Assume that three charges (q1, q2, and q3) are placed at the corners of an equilateral triangle with a side length of 1 cm, as shown in the figure below.
(a) Calculate the magnitude of the net force acting on charge q2 due to the other two charges.
(b) Draw a schematic diagram showing the directions of all the forces.
$$1 \mu C = q_2$$
$$q_3 = 2 \mu C$$
$$1 cm$$
$$q_1 = 1 \mu C$$
