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 [EAMCET (Med.) 1995; DPMT 2000]            

A)                         \[\frac{{{m}_{2}}g}{({{m}_{1}}+{{m}_{2}})}\]          

B)                           \[\frac{{{m}_{1}}g}{({{m}_{1}}+{{m}_{2}})}\]
