$A$ $2 \, kg$ block is lying on a smooth table and is connected to a body of mass $1 \, kg$ by a string passing over a pulley. The $1 \, kg$ mass is hanging vertically. Find the acceleration of the block and the tension in the string.
- A$3.27 \, m/s^2, 6.54 \, N$
- B$4.38 \, m/s^2, 6.54 \, N$
- C$3.27 \, m/s^2, 9.86 \, N$
- D$4.38 \, m/s^2, 9.86 \, N$
