Answer:
Explanation:
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
just substitute the values
