How a net force acts on 'Earth'?

In summary: N/m=0In summary, the net force on a ball is the force it applies to the air minus the force of the air on the ball. If there is a net force, the ball will accelerate.

You said''The fact that a force of 10N is applied to accelerate the object at first does not imply it applies a force of 10N on the second object''...So is this a fact that the the force applied on first object is not necessarily equal to the force it applies to the second object?...Because if it is not equal then of course there would be a net force on first object...
Yes, these are totally unrelated issues.

And you can extend post #26 to calculate the net force on M1.

The three laws of Newton are more clearly stated in Newton's Law: F=ma. This is most powerful statement in all of science.

F=ma is the second law. The third law might be phrased as ##F_{ab} = -F_{ba}##
