An infinite line of positive charge lies along the y axis, with charge density ? = 2.20 µC/m. A dipole is placed with its center along the x axis at x = 23.0 cm. The dipole consists of two charges ±10.0 µC separated by 2.00 cm. The axis of the dipole makes an angle of 40.0° with the x axis, and the positive charge is farther from the line of charge than the negative charge. Find the net force exerted on the dipole.
