Question
A column of water has a height of 10 meters and a density of 1000 kg/m³. Calculate the pressure at the base of the column. Use the gravitational field strength of 9.81 N/kg Explain your answer using Pressure in liquids (physics only) and depth.
Answer
The pressure at the base of the column is 98100 Pa.
Explanation
A strong answer should address (Physics only) Calculate depth from pressure, density and gravitational field strength directly. Use the context of Pressure in liquids (physics only) within Pressure and pressure differences in fluids (physics only), then state the relevant forces or motion reasoning with units where needed. The answer is correct when it names the key physics quantity, keeps force and pressure distinct, and links the conclusion back to the approved learning objective.
Common mistake
Common Mistake in Depth Calculation
Students often confuse the relationship between pressure, density, and depth, leading to incorrect calculations of depth from pressure.
To fix this, remember to use the formula depth = pressure / (density x gravitational field strength) and ensure you understand how each variable interacts.
