    Relationship between buoyancy Force and the gravitational force between two bodies?

    Picture below. Both bodies are made of same material but the body placed in water had 2.4 times greater mass. What is the relationship between buoyancy Force and gravitational force between body in water and body in air? I have no clue how to solve this. I know that body with greater mass has...
