An infinite line of positive charge lies along the y axis, with charge density ? = 1.90 µC/m. A dipole is placed with its midpoint along the x axis at x = 22.00 cm. The dipole consists of two charges ±10.0 µC separated by 2.00 cm. The axis of the dipole makes an angle of 37.0° with the x axis, and the positive charge is farther from the line of charge than the negative charge.
(a) Find the magnitude of the force exerted on the negative charge of the dipole.
(b) Find the magnitude of the force exerted on the positive charge of the dipole.
(c) Find the magnitude of the net force exerted on the dipole.
(d) Find the magnitude of the net torque exerted on the dipole. Calculate the torque about the midpoint of the dipole.
