1. The problem statement, all variables and given/known data The diagram shows the electric field lines surrounding three electric charges. Assume that q1 + q2 = -2.43 µC. A) Calculate q2. B) Calculate q1. C) Calculate q3. 2. Relevant equations |Fe|= (k*|q1|*|q2|)/r^2 |E|=(k*|Q|)/r^2 k = 8.99*10^9 (N*m^2)/C^2 Fe = Electrostatic force between a pair of charges r = charge separation q1, q2 = charge magnitudes E = electric field Q = charged object 3. The attempt at a solution I am having a very hard time with this question. I'm not sure where to start. Based on the diagram I assume that q1 and q3 will be equal in charge and magnitude but am not sure where to go from here. Any help would be greatly appreciated!
