Question

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 frictional force on block C

Quantrex Academy · Accepted Answer

Correct answer: B. 1.6 N

m _ c g =2 10 3 5 =12 ~N f_ = m _ c g =0.1 2 10 4 5 =1.6 ~N hence f =1.6 ~N
