Use the following information to answer this two-dimensional vector-skills question.Two point charges are located near point P, as shown below.Written Response—10 marks2. Determine the net electric field at point P that is caused by the two point charges. Aspart of your response, sketch arrows showing the electric field at P due to q A and theelectric field at P due to q B , explain how you determined the direction of these arrows.Sketch a vector-addition diagram consistent with the vector-analysis method you arechoosing. State all necessary physics concepts and formulas.Marks will be awarded based on your vector diagrams, the physics that you use, andthe mathematical treatment you provide.47
