An infinite line of positive charge lies along the y axis, with charge density = 2.40 μC/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 39 degree with the x axis, and the positive charge is farther from the line of charge than the negative charge.
(a) Obtain the magnitude of force exerted on negative charge of the dipole.
(b) Obtain the magnitude of the force exerted on the positive charge of the dipole.
(c) Obtain the magnitude of net force exerted on dipole.
(d) Obtain the magnitude of the net torque exerted on the dipole.
(e) Find the torque about the midpoint of the dipole.
