Given that the total mass of the Eiffel Tower is about 10,000 tonnes. The base of the tower consists of four feet, each of which is a square of side 25 m. The Great Pyramid of Giza is estimated to have a mass of about 6 million tonnes and its square base has a side of 230 m. Compare the pressure exerted on the ground by the Eiffel Tower and the Great Pyramid of Giza to the air pressure, which is about 101,000 Pa.

On Venus, the atmosphere is much denser than on Earth. As a result, the surface pressure is about 9.2 MPa. 870 m above the surface, the pressure drops to 8.7 MPa. The density of the atmosphere is 65 kg m−3. By calculating the difference in pressure, calculate the gravitational field strength g on Venus.
