well the ans is b option .


for this question you must know that when the string is cut the spring force does not change immidietly,


 


so before cutting,at b


mg=kx


at a,


mg +kx=tension


now after cutting,


 


at b,


mg=kx (as the spring force does not change)


at a,


mg+kx=ma


as kx =mg


then a=2g.
