A partially evacuated vertical cylindrical container is covered by a circular lid
tat makes an airtight seal. The pressure in the room surrounding the container is 1.01 × 105 N/m?, and the
pressure inside the container is 0.47x 105 N/m? The lid has radius 0.20 m and weight 200 N. The minimum
upward applied force required to lift the lid is most nearly:
