An electric dipole is formed from +/- 5.0 nc point charges spaced 3.0 mm apart. the dipole is centered at the origin, oriented along the y-axis. part a what is the electric field strength at point (x, y) = (25 mm, 0 cm)? express your answer using two significant figures. part b what is the electric field strength at point (x, y) = (0 cm, 25 mm)? express your answer using two significant figures.
