Which will exert more pressure 100 kg mass on an area of 10m2 or 50kg mass on an areaof 4 m2? (Take g = 10 m/s2)
Question
Which will exert more pressure 100 kg mass on an area of 10m2 or 50kg mass on an area of 4 m2? (Take g = 10 m/s2)
Solution
To solve this problem, we need to use the formula for pressure which is:
Pressure = Force/Area
Force is the product of mass and acceleration due to gravity (g).
- For the 100 kg mass:
Force = mass * g = 100 kg * 10 m/s² = 1000 N
Pressure = Force/Area = 1000 N / 10 m² = 100 N/m²
- For the 50 kg mass:
Force = mass * g = 50 kg * 10 m/s² = 500 N
Pressure = Force/Area = 500 N / 4 m² = 125 N/m²
So, the 50 kg mass on an area of 4 m² will exert more pressure.
