a solid aluminum ingot weighs 89N in the air. what is its volume? (b) the ingot is suspended from a rope and totally immersed in water. What is the tension in the rope?
Now in the water, it has the same mass, and the same volume. But it has a force of bouyancy equal to the weight of the displaced water.
weight in water=89N-bouyancyforce
