so what's ur final decision?

I;m not getting what you mean. Please elaborate

in the ques that i have attached as image with this thread.. I did it as an can be solved to \sqrt{}n by rationalising it. So as squre root of every natural no. 'n' is smaller than squre root of 'n+1' then in this ques. possible values comes out to be zero. Am i Right?

ok i got your this point, and my point of left and right is wrong. Now after this what?

yes. And by it i mean that the wire system LM on both (left and right) side is coated with soap film.

this wire system is 2dimensional or 3d? And sliding has occurred from LM to L'M' or reverse?

can you mark that area it in figure?

please elaborate how increase in surface area= 2lx. It simply makes no meaning that due to 2 surfaces total area becomes twice or 2lx

i'm not getting what you mean.

Issue is still same In my thread I've asked why increase in surface area is taken as 2lx instead of lx.

I too can see. But Thats for surface tension according to me. As you can see in figure this topic is part b). Actually part one is for liquid drop. In that surface tension is taken to b 'T'. But as for a liquid bubble there are to effective surfaces, surface tension comes out to b '2T'.

CAn you explain meaning of edge, I've never used this term in surface tension problems. And in my view surface tension can't bear 50kg force.

Now check this one. iN THIS for a liquid bubble which too have 2 sides increase in surface area is taken as 4pi*r^2 not 2*4pi*r^2

Then you tell me what is this?
