A block A of mass m_1 rests on a horizontal table. A light string connected to it passes over a frictionless pulley at the edge of table and from its other end another block B of mass m_2 is suspended. The coefficient of kinetic friction between the block and the table is \mu_k.When the block A is sliding onthe table, the tension in the string is :-
- A\(\frac{(m_2-\mu_km_1)g}{(m_1+m_2)}\)
- B\({m_1m_2(1+\mu_k)g}/(m_1+m_2)\)
- C\({m_1m_2(1-\mu_k)g}/(m_1+m_2)\)
- D\(\frac{(m_2+\mu_km_1)g}{(m_1+m_2)}\)
✓ Correct answer: B
