A

`sqrt((gL)/2)`

B

`sqrt(2gL)`

C

`sqrt(gL)`

D

none of these

A thin uniformed rod of mass m and length L is hinged at one end and from other end a light string is attached. The string is wound over a frictionless pullely (having mass 2m ) and a block of mass 2m is connected to string on other side of pulley as shown. the system is released from rest when the rod id making an angle of 37^(@) with horizontal. Based on above information answer the following question : Just after releases of the system from rest acceleration of block is
