A jet plane having a cabin of length = 50 m flies along the horizontal with an acceleration `a = 1 m//s^(2)`. The air density in the cabin is `rho = 1.2 xx 10^(-3) g//cm^(3)`.
What is the difference between the atmospheric pressure and the air pressure exerted on the ears of the passengers sitting in the front, middle, and rear parts of the cabin?
