Paragraph: In the shown figure m_A, m_B and m_C are the masses of the three blocks, the incline is frictionless m_A=5 ~kg , m_B=10 ~kg , m_C=2 ~kg . coefficient of friction between A and B is 0.5 and between B and C is 0.1 ( . Take g =10 ~m / s ^2 ) On the basis of above data answer the following questions. Question: What is the tension in the rod
