Where q1 = q2 = q. 92 2. -3 -2 -1 1. -1 -2. 91 Once you determine the electric field analytically, answer: What would be the force on a test charge Q located at point P? Justify your answer. In case the sign of both charges is exchanged to a negative sign, what would be the field on the point P in this case? Give as detailed an explanation as possible. Note: You do not need to redo the procedure
