As shown in the figure, the closed container filled with water is placed on the horizontal table, and the ratio of the upper and lower bottom areas is 4:1. At this time, the pressure of water on the bottom of the container is f, and the pressure is p. when the container is placed on the horizontal table after being inverted, the pressure and pressure of water on the bottom of the container are () A. F,PB. 4F,PC. 14F,PD. F,4p

The liquid will produce pressure on the bottom and side wall of the container. The greater the depth of the same liquid is, the greater the pressure is. After the container is inverted, if the liquid depth is not changed, the pressure will remain unchanged, which is still P. according to f = PS, if s is expanded to 4 times, the pressure will also become 4f
