Q. A block of mass $m_{1}$ reacts on a horizontal table. A string tied to the block is passed on a frictionless pulley fixed at the end of the table and to the other end of string is hung another block of mass $m_{2}$. The acceleration of the system is
A) $\frac{m_{2}g}{(m_{1} + m_{2})}$
B) $\frac{m_{1}g}{(m_{1} + m_{2})}$
C) $g$
D) $\frac{m_{2}g}{m_{1}}$
Explanation
The correct answer is Option A: $\frac{m_{2}g}{(m_{1} + m_{2})}$.
