The density of metal cylinder a is 5 * 10 cubic kilogram per cubic meter, The density of metal cylinder a is 5 * 10 cubic kilogram per cubic meter, the volume is 2 * 10 negative cubic meter, and the bottom area is 1 * 10 negative quadratic square meter. The height of thin-walled cylindrical container B is 0.3m, the bottom area is 2 * 10 negative quadratic square meter, and the water depth in the container is 0.25m If the object a is immersed in the water of the container B with a rope, calculate the increase of the water pressure on the bottom of the container B
When a is put into the container, the water surface in the container will rise, so the pressure at the bottom of the container will increase;
But there is a limitation in this problem, that is, the water in the container is almost full, so the water will overflow when the nail is put in, so the water depth in the container is at most the concentration of the container
V a = 2 * 10 ^ (- 3)
VN = 2 * 10 ^ (- 2) * (3-0.25) = 1 * 10 ^ (- 3)
