1. The problem statement, all variables and given/known data I place a water filled beaker on an electronic balance and zero the reading. Meaning the balance will not be measuring the weight of the water and the beaker. a.) If a ball is resting at the bottom of the beaker. What would the balance be measuring? b.) If I immersed and suspend a ball with a string in the water and not touching any sides. What will the electronic balance be measuring? c.) This time I lift the ball up from below, but not getting it out of the water. What would the balance be measuring? 2. Relevant equations 3. The attempt at a solution a.) Looking at the free body diagram, I guess the balance shows the normal force. Since N = mg - B where B is buoyancy. b.) Since it is suspended, T + B = mg whereby T is tension. It is in equilibrium so what would the balance be measuring? Is it the mass of the displaced water according to Archimedes Principle? If it is so, does part a include the mass of the displaced water too? c.) When I lift the ball up, fluid resistance f is pushing it down. Hence F = T + B - mg - f. The resultant force is upwards, but what is the balance measuring?
