Question

A block A of mass m₁ rests on a horizontal table. A light string connected to it passes over a frictionless pully at the edge of table and from its other end another block B of mass m₂ is suspended. The coefficient of kinetic friction between the block and the table is $\mu $_k. When the block A is sliding on the table, the tension in the string is

${{{m_1}{m_2}(1 + {\mu _k})g} \over {({m_1} + {m_2})}}$

${{{m_1}{m_2}(1 - {\mu _k})g} \over {({m_1} + {m_2})}}$

${{\left( {{m_2} + {\mu _k}{m_1}} \right)g} \over {\left( {{m_1} + {m_2}} \right)}}$

${{\left( {{m_2} - {\mu _k}{m_1}} \right)g} \over {\left( {{m_1} + {m_2}} \right)}}$
