QAIPM-2015-Ph-1355: NEET 2015 Physics - Class 11 AIPM-2015-Ph-1355 Solution: A block A of mass \(m_1\) rests on a horizontal table. A light…

A block A of mass m1m_1 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 m2m_2 is suspended. The coefficient of kinetic friction between the block and the table is μk\mu_k. When the block A is sliding on the table the tension in the string is m1m2(1+μk)gm1+m2\frac{m_1m_2(1+\mu_k)g}{m_1+m_2} m1m2(1−μk)gm1+m2\frac{m_1m_2(1-\mu_k)g}{m_1+m_2} (m2+μkm1)gm1+m2\frac{(m_2+\mu_k m_1)g}{m_1+m_2} (m2−μkm1)gm1+m2\frac{(m_2-\mu_k m_1)g}{m_1+m_2}

Multiple Choice Options

  • A m1m2(1+μk)g(m1+m2){{{m_1}{m_2}(1 + {\mu _k})g} \over {({m_1} + {m_2})}} ( m 1 _ + m 2 _ ) m 1 _ m 2 _ ( 1 + _ k _ ) g _
  • B m1m2(1−μk)g(m1+m2){{{m_1}{m_2}(1 - {\mu _k})g} \over {({m_1} + {m_2})}} ( m 1 _ + m 2 _ ) m 1 _ m 2 _ ( 1 _ _ k _ ) g _
  • C (m2+μkm1)g(m1+m2){{\left( {{m_2} + {\mu _k}{m_1}} \right)g} \over {\left( {{m_1} + {m_2}} \right)}} ( m 1 _ + m 2 _ ) ( m 2 _ + _ k _ m 1 _ ) g _
  • D (m2−μkm1)g(m1+m2){{\left( {{m_2} - {\mu _k}{m_1}} \right)g} \over {\left( {{m_1} + {m_2}} \right)}} ( m 1 _ + m 2 _ ) ( m 2 _ _ _ k _ m 1 _ ) g _
