Question

A force of 50N acts on an area of 25cm square, calculate the pressure produced.

Answer 1

Answer:

Force= 50N

Area = side of square ^2= 25^2 cm^2 = 625 cm^2 = 0.0625 m^2

Pressure = force/area= 50/0.0625 = 800 Pa

Answer 2

The pressure produced is 20,000 N/m².

Given - Force and area

Find - Pressure

Solution - Pressure, force and area are related with the given formula -

Pressure = Force/Area

Converting area into m².

1 m² = 10⁴ cm²

25 cm² = 25/10⁴

25 cm² = 0.0025 m²

Pressure = $\frac{50}{0.0025}$

Pressure = 20,000 N/m²

Hence, the pressure produced is 20,000 N/m².
