0A block A of mass \( m_{1} \) rests on a horizontal table. A
\( \mathrm{P} \)
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 on the table, the tension in the string is:
(1) \( \frac{\left(m_{2}-\mu_{k} m_{1}\right) g}{\left(m_{1}+m_{2}\right)} \)
(2) \( \frac{m_{1} m_{2}\left(1+\mu_{k}\right) g}{\left(m_{1}+m_{2}\right)} \)
(3) \( \frac{m_{1} m_{2}\left(1-\mu_{k}\right) g}{\left(m_{1}+m_{2}\right)} \)
(4) \( \frac{\left(m_{2}+\mu_{k} m_{1}\right) g}{\left(m_{1}+m_{2}\right)} \)
