because bottle X:p,2V . Y:2p, V . Both x and y at same temperature , so constant for both is 2Vp . When valve opened new volume is 3V but the constant stays the same because temperature stays the same no ?

Just got a question about this question . I'm using Boyle's law for this but am getting the new pressure as 2p/3 ? Both bottles are at the same temperature and so will both have same constants of 2Vp. So once the valve is opened total volume is now 3V however there is no change in temperature...

Yeah all makes sense now , I see what you mean I can just equate like a normal statics question. Thanks a lot for everyones help and time.

Ok I've found the anticlockwise and clockwise moments, so net moment is 0 . But still haven't found a way to prove the upward and downward force on the plank is 0.

How do I find the force though , I have equated those but just proves they're are equlibrium like you said, I can't see where I can equate for F(force)

I did 2Xw=200X0.5 w=50N
