If they are pulling it at opposite direction:

Fnet=Fn+Fg
=10units +(-10 units)
=0
In this situation,the force is balanced.


If they are pulling it at the same direction:

Fnet=Fn+Fg
=10 units+(10 units)
=20

In this situation,the force is unbalanced and the object will move to the direction which the boy and the girl is pulling it.
