An electric dipole has charges of 4.55pC that are separated by 6.75cm. The dipole lies on the x-axis, its positive end lies on the +x-axis, and its center is at the origin. Located at y = +4.00cm is a point charge carrying a charge of -2.85pC.
A) Determine the net force on the dipole.
B) Determine the initial center of mass acceleration of the dipole (including direction) if it has a total mass of 8.05ng.
C) Determine the torque on the dipole about its center of mass.
