In the diagram, A and B represent small spherical charges: q1 = -8.0 C located at point A and q2 = 5.0 C located at point B. Point A is 50.0 cm from Point B and 20.0 cm from point C.

a. What is the magnitude and direction of the electric field at point C? [6]

b. If a 10.0 C charge is placed at point C, what force would it experience? [2]

c. What would the electric potential be at point C? [4]

d. If a 10.0 C charge is placed at point C, what electric potential energy would it have? [2]
