Question

the mass of brick id 2.5kg.its dimensions are 10cm*5cm*2cm.what will be its pressure exerted by it on the ground if it is resting on a10cm*5cm base 5cm*2cm base take 1kg wt=10N

Answer 1

By 1 kg wt = 10 N it means g = 10 m/s²

Pressure = Force / Area in contact with ground
= mg / A

1.
Pressure = (2.5 kg × 10 m/s²) / (10 cm × 5 cm × 10^-4 m²/cm²)
= 5000 pascals
= 5 kilo pascals

2.
Pressure = (2.5 kg × 10 m/s²) / (5 cm × 2 cm × 10^-4 m²/cm²)
= 25000 pascals
= 25 kilo pascals

Answer 2

1 kg wt = 10 N means g = 10 m/s²

Pressure = Force / Area in contact with ground  = mg / A

Pressure = (2.5 kg × 10 m/s²) / (10 cm × 5 cm × 10^-4 m²/cm²)

= 5000 pascals

= 5 kilo pascals

Pressure = (2.5 kg × 10 m/s²) / (5 cm × 2 cm × 10^-4 m²/cm²)

= 25000 pascals

= 25 kilo pascals
