A block of mass ${m_1}$ rests 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
$\frac{{{m_2}g}}{{({m_1} + {m_2})}}$
$\frac{{{m_1}g}}{{({m_1} + {m_2})}}$
$g$
$\frac{{{m_2}g}}{{{m_1}}}$
A block of mass ${m_1}$ rests 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
$m_{2} g=\left(m_{1}+m_{2}\right) a$
$a=\frac{m_{2} g}{m_{1}+m_{2}}$
