21 =-6 HC d =0.6 m 23 =-2 UC Figure 2: Picture of the setup in problem 2. 2.) Three charged particles are located at the corners of an equilateral triangle (all sides are the same length). See Fig. 2. (a. ) Calculate the net electric field (magnitude and direction) at the point P located in the middle of the triangle base. (b.) Calculate the electric potential at the point P. (c. ) Calculate the minimum work done to move a charge q = 3 uC from very far away to the point P. (d.) Calculate the electrostatic force (magnitude and direction) exerted on q when it is placed at point P
