What force does the 4.0 kg object exert on the 10 kg object when the two are moving together?
Ofcourse, I know I did not put the previous, required information in order to solve this question. I would like to know in general how to find the magnitude of force one object exerts on another in this type of situation. Any help is greatly appreciated :)

I assume they mean the force of gravity between them:
F=(G(m1)(m2))/r^2 That will be the magnitude of the force between the two objects where 'G' is the gravitational constant (i believe 6.67E11) and 'm1'&'m2' are the mass of the two objects and 'r' is the distance between them.

no I think he means contact forces.
You sum the forces in each direction, then solving for the force that you wish to find. Draw a Force Diagram

zero.
If the two are moving together there is force between them
