I did some calculations wrong but I figured out that using the ecuation F= m*a it resulted that the tension is 37.5 Newtons . My teacher told us that the result is 30 Newtons , equal to the lower mass object but I can’t figure out why ..

hello ! I tried diving the chain into 2 separate parts based on the length and the mass of the chain . The first part is the one on the right and has a mass of 10*8/16 which is 5 kg and the other being 3 kg , being linked by a wire with no mass . The tension resulted is negative now ..
