Three charged objects are arranged as shown in figure 5. -2nC 3cm 1nC 51.13 3cm 5cm -2nC 1cm P Figure 5) the arrangement of three charges. A. Roughly sketch the electric field lines around the charges. You may use words to describe features if you feel you cannot adequately draw them. B. What is the net electric field at point p? Make sure to indicate strength and direction and show your working. (5 marks) C. If we placed a charge of -2 nC at point p, what force would it experience? Make sure to indicate strength and direction and show your working. D. If these are the only charges present, write an expression for the strength of the electric field at a distance, r, extremely far away from the charges. Explain/justify how you got your expression.
