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