hi there......
Since the Earth's mass is positive and the -1 kg mass is negative, there will be a repulsive force acting on the mass. ... The conservation of energy would not be violated, since the total mass of the system is zero, so its kinetic energy is alsoalways zero, regardless of the speed of the mass dipole
