求液体对容器底的压强和整个容器对支承面的压强这类题中 ,很多同学模糊不清常出错 ,下面我们看以下几题。例题如图 1,装有水的轻质薄塑料容器 (容器重忽略不计 )放在水平桌面上 ,设水对容器底的压强为P1,整个容器对桌面的压强为P2 ,则它们之间的关系是
Seeking the pressure of the liquid on the bottom of the container and the pressure of the entire container on the supporting surface, many students are confused and often mistakes. Here we look at the following questions. An example is shown in Figure 1. A light, thin, plastic container filled with water (negligible container weight) is placed on a horizontal table. The pressure on the bottom of the container is P1. The pressure on the entire container is P2. The relationship is
