As in the diagram three blocks connected together lie on ahorizontal frictionless table and pulled to the right with a force F=50 N if m_(1)=5kg m_(2)=10 kg and m_(3)=15 kg find the tensionsT_(1) and T_(2)

Answer»

Solution :
ACCELERATION acquired by all blocks a `= (T_(3))/(m_(1)+m_(2)+m_(3)) = (36)/(36)` 1 `MS^(-2)`
`:.` TENSION`T_(2) = (m_(1) + m_(2))` a
`= ( 1+8) xx 1 = 9` N
