Question: A 200m spherical particle has been fixed to a spatula using super-glue and has been very slowly brought downward to a 5nm (nanometre) separation distance

A 200m spherical particle has been fixed to a spatula using

A 200m spherical particle has been fixed to a spatula using super-glue and has been very slowly brought downward to a 5nm (nanometre) separation distance with another spherical particle with the diameter of 100m which is free standing on a surface (Figure 2). If it the spatula is very slowly moved upward, determine if the 100m particle can be lifted in this way. The density of both particles is 1200kg/m3. The experiment is carried out in air. The Hamaker constant for both particles in air is 501020J.
