Consider 3 positive charges q1, q2 and q3 as shown in the figure below. a) Without calculation, draw the force F1 exerted on q3 by q1 and the force F2

exerted on q3 by q2. b) What is the total force F exerted on q3 by both charges q1 and q2? Draw F on the figure above. c) What will happen to the force F1 if we increase the value of the charge q1? Explain your answer. d) What will happen to the force F2 if were place q2 by a negative charge? Explain your answer.
