Question
Calculate the pressure at a depth of 10 meters in water, given that the density of water is 1000 kg/m³ and the gravitational field strength is 9.81 N/kg Explain your answer using Pressure in liquids (physics only) and depth.
Answer
The pressure at a depth of 10 meters in water is 98100 Pa.
Explanation
A strong answer should address (Physics only) Calculate pressure from depth, 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 Pressure Calculation
Students often confuse the units of pressure, using N/m instead of Pa.
Remember that pressure is measured in pascals (Pa), where 1 Pa = 1 N/m². Always convert your force and area to the correct units before calculating pressure.
