Pressure and buoyancy 20. (09 Ningbo) as shown in the figure, there is a certain amount of water in an inclined cylindrical container. There is a 5N ball floating on the surface of the container. If the ball is taken out, the decrease of water pressure on the bottom of the container is () A. Greater than 5N B. equal to 5N C. Less than 5N D. It depends on the size of the ball

Choose B
When the ball floats on the water, its gravity is equal to the buoyancy of 5N,
Take out the 5N ball and reduce the pressure by 5N
