A certain diving bell for use in the ocean has a square window measuring \(0.250 \mathrm{~m}\) on each side. The inside of the bell is pressurized and maintained at a pressure of \(2.00 \mathrm{~atm}\). How deep can this bell be lowered before the vector sum of forces exerted by the seawater on the window exceeds \(195 \mathrm{kN}\) ? The mass density of seawater is \(1025 \mathrm{~kg} / \mathrm{m}^{3}\).
