Hy tiba.. For maximum mass of greased needle which floats on water... U can use the concept of balancing force... The downward force ie weight is equal to force due to surface tension.. So 2TL=mg, where T is the surface tension and L is its length... From here you can get maximum mass m... Hope U like it..
