Three blоcks аre in cоntаct with eаch оther on a frictionless surface. m1 = [m1] kg, m2 = [m2] kg, and m3 = [m3] kg. An external force F is applied to m3, causing the entire system of blocks to accelerate at [a] m/s². What is the magnitude of the force exerted by m3 on m2? Provide your answer in newtons (N).
