问题 选择题

如图示,甲、乙两个容器都是圆柱形的,但乙容器比较粗.两容器中盛的都是水,放在水平桌面上时液面一样高.那么下列说法中正确的是(  )

A.甲容器中的水少些,所以水对甲容器底的压强小些

B.乙容器底面积大些,所以水对乙容器底的压强小些

C.水对两容器底的压力相等,压强也相等

D.水对两容器底的压力不相等,但压强相等

答案

∵甲、乙两个容器都是圆柱形的,

∴水对容器底的压力:

F=ps=ρghs=ρvg=mg=G,

即:水对容器底的压力等于水重;

∴甲容器中水对容器底的压力比乙容器中水对容器底的压力大;

由题知,两容器放在水平桌面上时,液面一样高,

∴两容器内水深h相同,

∵p=ρgh,装的都是水,

∴水对容器底的压强相同.

故选D.
