An airtight box has a removable lid of area 1.0 multiplied by 10-2 m2 and negligible weight. The box is taken up a mountain where the air pressure outside the box is 0.70 multiplied by 105 Pa. The inside of the box is completely evacuated. What is the magnitude of the force required to pull the lid off the box?
