Question 38

A flat, circular optical sensor window on a deep-sea research probe has a surface area of 0.024 m2.

At a certain depth, the hydrostatic pressure of the seawater acting on the window is 4.5 MPa (4.5 × 106 Pa).

Calculate the magnitude of the force exerted by the seawater on the window.

Use the equation:

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