A particle carrying the charge +q is located at x = −2d. A particle carrying the charge −4q is located at x = 3d. If V (∞) = 0, where on the x-axis is V = 0?

An infinite line of positive charge lies along the y axis, with charge density = 1.30 μC/m. A dipole is placed with its center along the x axis at x = 22.0 cm. The dipole consists of two charges ±10.0 μC separated by 2.00 cm. The axis of the dipole makes an angle of 45.0° 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.
