-Looking at the electric field lines you drew for the "​dipole"​ arrangement,​ where is the field the most dense, close to the + and - charges or closer to the horizontal center line of the graph? ​Compare your observation with the sketch shown in Ch15 sheet 26.+Looking at the electric field lines you drew for the "​dipole"​ arrangement,​ where is the field the most dense, close to the + and - charges or closer to the horizontal center line of the graph?

If you replace the negative charge in the dipole by a positive charge, is the pattern of the electric field lines the same as measured for the +/- dipole? ​ If you replace the negative charge in the dipole by a positive charge, is the pattern of the electric field lines the same as measured for the +/- dipole? ​
