An electric dipole has charges of ± 4.55pC that are separated by 6.00 cm. The dipole lies on the x-axis and its center is at the origin. Located at y = + 4.00 is a point charge carrying a charge of – 2.50pC.
(a) Determine the net force on the dipole and its initial center of mass acceleration (including direction) if it has a total mass of 7.25 ng.
(b) Determine the torque on the dipole about its center of mass, including direction.
