An iron ball o fradius 1 m and density ...

An iron ball o fradius 1 m and density `8000 kg m^(-3)` is placed in water . A bubble of radius 1 cm at a distance 1.5 m from the centre of the ball . Will there be a force of attraction or repulsion between them and what will be the magnitude of this force ? (Neglect the mass of air and take ` G=6.67 xx 10^(-11)`.)
