Blоck 1 оf mаss is in cоntаct with block 2 of mаss . The two blocks are on a horizontal surface with negligible friction. Suppose a horizontal force is applied to the left side of block 1 and a second horizontal force is applied to the right side of block 2, as shown in the figure, with magnitudes satisfying . Let denote the force on block 1 due to the contact with block 2. Let denote the magnitude of the acceleration of the blocks. Which of the following statements is true?
