106i too think surface tension because... the two layers of glass attract the water molecules equally hence it acts like an adhesive between the two glass plates
Two glass plates having a little of water in between cannot be easily separated because a)atmospheric pressure b)surface tension

62if it had to do with surface tension, wud it not have been equally tough to lift the glass plate from water?
I am not sure of this answer.. just guessing!
106but here there are two adhesive forces that act in equal and opposite directions hence it wud be tougher.... i dont know abt one plate only... consider a glass tumbler placed on some water on a table... it is difficult to lift out..
106well it can be air pressure and surface tension both dont u think bhaiyya?
1ans given is air pressure but i can't get why the ans is not surface tension
62yes I also think that it should be both surface tension and air pressure.
