(adsbygoogle = window.adsbygoogle || []).push({}); The situation is shown :-

All surfaces are frictionless. I am trying to find the max extension of the spring as the force is applied. Spring is massless.

F=ma

I tried drawing FBDs for block A and B:-

F-kx=Ma(from fbd of A)

kx=ma(from fbd of B)

, we get

x=Fm/k(M+m)

Is this correct??

Also can anyone explain how to visualize when spring if stretched from both sides? How do you then apply Hooke's law?
