An infinite line of positive charge lies along the y axis, with charge density 2.80 C/m. A dipole is located with its midpoint along the x axis at x = 30 centimeter. The dipole consists of two charges ±10.0 μC separated by 2 centimeter. The axis of the dipole makes an angle of 31 degree with the x axis, and the positive charge is farther from the line of charge than the negative charge.
