The density of air on the Earth decreases almost linearly with height from 1.22 kg m⁻³ at sea level to 0.74 kg m⁻³ at an altitude of 5000 m. Atmospheric pressure at the Earth's surface on a particular day is 100 000 Pa. The value of g between the Earth's surface and an altitude of 5000 m can be considered to have a constant value of 9.7 m s⁻². What will be the atmospheric pressure at an altitude of 5000 m?

1. A36 000 Pa
2. B48 000 Pa
3. C52 000 Pa
4. D59 000 Pa
