The plastic tube in Fig. has a cross-sectional area of 5.00 `cm^(2)`. The tube is filled with water until the short arm (of length d = 0.800 m) is full. Then the short arm is figure sealed and more water is gradually poured into the long arm. When the total height of water in the long arm reaches 2.80 m, the seal is on the verging of popping. What force is then on the seal?
