Part A
An electric dipole is made of two charges of equal magnitudes and opposite signs. The positive charge, q = 7.0 C, is located at the point (3.0 cm, 0 cm, 0) and the negative charge, -q, is located at the point (0 cm, 0 cm, 0). The dipole is oriented along the y-axis. Find the electric field at a point P located at (2.2 cm, 0.3 cm, 0) due to the dipole.
