    1. The problem statement, all variables and given/known data

    A ball has a density of 900kg/m^3 and it's volume is 0.03m^3. To submerge in water the ball must be held down by the force. What is the force required to keep the ball submerged.

    2. Relevant equations

    3. The attempt at a solution
    Not sure what equation to use to find the force/ how to do the problem

    Consider the following:
    - What are the forces acting on the ball when it is underwater? (Draw a force diagram as aid)
    - What should the net force be to keep it at rest underwater?
