Question

2)

A force of 20 N acts over a surface having an area 4cm2

.What is the pressure on

this surface?​

Answer 1

Explanation:

Pressure = Force / Area

= 20 N / (4 cm² × 10⁻⁴ m²/cm²) ………[∵ 1 = 10⁻⁴ m²/cm²]

= 5 × 10⁴ pascals

= 50 kilo pascals

Pressure exerted by force is 50 kilo pascals
