Two blocks of masses \( m_{1} \) and \( m_{2} \) are connected as shown in the figure. The acceleration of the block \( m_{2} \)
\( \mathrm{P} \) is

W
(1) \( \frac{m_{2} g}{m_{1}+m_{2}} \)
(2) \( \frac{m_{1} g}{m_{1}+m_{2}} \)
(3) \( \frac{4 m_{2} g-m_{1} g}{m_{1}+m_{2}} \)
(4) \( \frac{m_{2} g}{m_{1}+4 m_{2}} \)
