The momentum of an object is given by the product between its mass and its velocity:
where m is the mass and v the velocity.
For the object in our problem, m=10 kg and v=10 m/s, therefore its momentum is

These two pieces which are oppositely charged attracts each other, this shows that electric charge is conserved.
