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 knetic friction between the block and table is $μ_{k}$ . When the block $A$ is sliding on the table, the tension in the string is.

\frac{( m _{2} + μ _{k} m _{1} ) g}{m _{1} + m _{2}}

\frac{( m _{2} - μ _{k} m _{1} ) g}{m _{1} + m _{2}}

\frac{m _{1} m _{2} ( 1 + μ _{k} ) g}{m _{1} + m _{2}}

\frac{m _{1} m _{2} ( 1 - μ _{k} ) g}{m _{1} + m _{2}}
