Expert Answer

Step 1

(a) The force F21 exerted on q2 by q1 is repulsive since both the charges are positive. The magnitude and direction of force are given by,

fullscreen
Step 2

(b) The force F23 exerted on q2 by q3 is attractive since the charges are opposite. The magnitude and direction of force are given by,
