A block A of mass $\displaystyle \mathrm{m}_1$ 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 $\displaystyle B$ of mass $\displaystyle m_2$ is suspended. The coefficient of kinetic friction between the block and the table is $\displaystyle \mu_{\mathrm{k}}$. When the block A is sliding on the table, the tension in the string is :
Official answer
(3)
$\displaystyle \frac{m_1 m_2\left(1+\mu_k\right) g}{\left(m_1+m_2\right)}$
