1. Three point charges are located at the corners of an equilateral triangle with each side of length l = 2.0 cm. A four charge is placed exactly in the center of the triangle, as shown in the figure below. Assuming that q2 = +5 uC, charge q1=q3= +4.0 uC and q4 = -2.0 uC determine the following:

a. What is the force in unit vector notation on q4 due to the other three charges?

b. What is the net electric field due to all the carges at the location of charge q4?

c. What is the net electric potential due to all the charges at the location of charge q4?
