let the weight of block a be M and that of b be m
Mgh>1/2kx^2
at least
Mg=kx

tension in string of A is twice that of string of B. let tension in A be 2T & in B T. so, whatever distance A will move, B will move half that distance. by conservation of energy,
mgx = 1/2k(x/2)^2
solving for m, we get m = kx/8g.
tell me if its correct or not. sorry if i'm wrong.

Men have been taught that it is a virtue to agree with others. But the creator is the man who disagrees. Men have been taught that it is a virtue to swim with the current. But the creator is the man who goes against the current. Men have been taught that it is a virtue to stand together. But the creator is the man who stands alone. |

T = mg
T' = 2T = 2mg
T' + kx = Mg ( kx is the restoring force by spring. x is extension of spring)
2mg + kx = Mg
m = (Mg - kx) / 2g
