QA = QB = 1.5 C, and QC = −3.0 C are located as shown in the diagram. a) Calculate the electric field from charges B and C at the location of point A. In other words, you may want to start by redrawing the diagram with charge A replaced by point P. Draw the electric field contributions from B and C at that point. b) What is the net electric force on QA?
