A small rigid object carries positive and negative 4.00 nC charges. It is oriented so that the positive charge has coordinates (-1.20 mm, 1.50 mm) and the negative charge is at the point (1.40 mm, -1.30 mm). (a) Find the electric dipole moment of the object. The object is placed in an electric field = (7800 - 4900 ) N/C.
