1. The problem statement, all variables and given/known data Three blocks are in contact with each other on a frictionless horizontal surface. A 503 N horizontal force is applied to the block with mass of 2.6 kg as shown in the ﬁgure below. The acceleration of gravity is 9.8 m/s^2. What is the magnitude of the force between the block with mass 5.8 kg and 8.3 kg? 2. Relevant equations 3. The attempt at a solution I understood the other parts but i can't figure out this question.
