PS Three Coplanar Charges Figure 2 F (net) F(1,3) F (2,3) Figure 1 4 m q2 - -3C q3 - +5C 3 m qi - +3C Three coplanar charges are positioned relative to one another as shown in Figure 1. The imaginary line that joins q1 and q2 is perpendicular to the imaginary line that joins q2 and q3. q2 is negative and that q1 and q3 are positive thus q1 repels (push) q3 and that q2 attracts (pulls) q3. Determine the following: The attractive electric force that exists between The repulsive electric force that exists between q2 and q3, F(2,3) q1 and q3, F(1,3) The net electric force F(net) that acts on q3 due to q1 and q2 as shown in figure 2. Use cosine law.
