- 9. It is known that the standard value of 1 standard atmospheric pressure is about 10 to the fifth power Pascal. Xiao Ming wants to explore the atmospheric pressure through experiments. His experimental scheme is to press the plastic hook suction cup dipped in water on a smooth horizontal table, squeeze out the air inside, and measure the reading with a spring dynamometer. This is the pressure of the atmosphere on the suction cup: then try to measure the contact area between the suction cup and the table, Then calculate the atmospheric pressure Q: Xiao Ming has chosen a spring dynamometer with a measuring range of 100 n. please explain by calculation the size of the suction cup with the bottom area at least so as to carry out the experiment smoothly? (assuming that the air in the suction cup is completely squeezed out)
