上海市第十四届初中物理竞赛(上科杯)初赛试题中第29题:如图1所示,两只完全相同盛水容器放在磅秤上,用细线悬挂质量相同的实心铅球和铝球,全部浸入水中,此时容器中水面高度相同。设绳的拉力分别为了T_1和T_2,磅秤的读数分别为F_1和F_2,则 In the preliminary questions of the 14th Shanghai Junior Physics Competition (Shangkee Cup), Question 29: As shown in Figure 1, two identical water containers are placed on the scales, and the solid shots and aluminum of the same quality are suspended by fine lines. The ball is completely immersed in water and the height of the water in the container is the same. Set the rope’s pull force to T_1 and T_2 respectively. Scale readings are F_1 and F_2 respectively.
