An electric dipole is formed from two charges, ±q, spaced 1.0 cm apart. The dipole is at the origin, oriented along the y-axis. The electric field strength at the point (x, y) = (0 cm, 10 cm) is 360 N/C.
a. What is the charge q? Give your answer in nC.
b. What is the electric field strength at the point (x, y) = (10 cm, 0 cm)?
