Question 40

The outer emergency door of a deep-sea bathyscaphe is rectangular, measuring 35 cm by 50 cm.

At its operational depth, the ocean water exerts a pressure of 4.2 × 105 Pa on the door.

Calculate the force, in newtons, exerted on the door by the water pressure.

Use the equation:

pressure=forcearea \text{pressure} = \frac{\text{force}}{\text{area}} pressure=areaforce​
