Question

Which will exert more pressure, 100kg mass on 10m square or 50kg mass on 2m square
​

Answer 1

P = F/A

Case 1:-

Mass of the object = 100 kg

∴ Thrust (F) = (100 kg)(9.8 m/s²) = 980 N

[F = m × a]

Area = 10 m²

∴ P = (980 N)/(10 m²) = 98 Pa

Case 2:-

Mass of the object = 50 kg

∴ Thrust (F) = (50 kg)(9.8 m/s²) = 490 N

[F = m × a]

Area = 2 m²

∴ P = (490 N)/(2 m²) = 245 Pa

Therefore, the object having a mass of 50 kg will exert more pressure on the surface.
