Two blocks are in contact on a frictionless table. A horizontal force F is applied to M2, as shown. If M1 = 1.81 kg, M2 = 3.26 kg, and F = 5.50 N, find the size of the contact force between the two blocks.

Let's analyze all the forces involved. Of course the weights are supported by the respective reactions of the table, hence there's no net force in the vertical direction. Now note that in the horizontal direction, we have that the force F acts on M2. This block in turn pushes M1 with the contact force T (the one we want to ...
Newton's second law is used to determine the size of the contact force between two blocks or difference masses.
