										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..
