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..

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
