An electric dipole consisting of two unlike charges, +12 nC and -12 nC, is placed along the x-axis. There are three test points a, b and c scattered in the xy plane (Fig.1). a) Draw the lines of electric field between the two charges b) Find the net electric field at points a, b and c c) How would a test charge move if placed at point a? d) Find the net electric force on a test charge of +1 pc placed at point c e) Find the potentials at points a, b and c b 4 cm +q 13 cm 6 cm 13 cm 4 cm -9
