Title: As shown in Fig. 1, a cylindrical water tank with a base area of 400 cm2 holds the appropriate amount of water, and a column mass with a mass of 1 kg, a height of 12 cm, and a cross-sectional area of 100 cm2 is used. The dynamometer is suspended so that it is immersed in water to a depth of 2 cm, the spring dynamometer is weighed from 0 to 10 N, and the scale is from 0 to 10 N to a length of 10 cm (take g=
