A cube with a gravity of 100 N and a side length of 20 cm is placed in the center of the experimental small square table. If the side length of the small square table is 10 cm, the pressure of the cube on the table is 0______ If the side length of a small square table is 50 cm, the pressure of the cube on the table is 0______ It's a handkerchief

If the side length of the small square table is L = 10cm, the stress area is s = (0.1M) 2 = 0.01m2, the pressure of the cube on the table is p = FS = 100n0.01m2 = 10000pa; if the side length of the small square table is L = 50cm, the stress area is s = (0.2m) 2 = 0.04m2, the pressure of the cube on the table is p = FS = 100n0.04m2 = 2500pa
