Question

C)The mass of the brick resting on the ground is 2.5 kg. The base area is 10X 5 cm. Find the pressure
exerted by it on the ground.(g=10m/s 2)

Answer 1

Answer:

2.5 pascals

Explanation:

$given$

$mass = 2.5kg$

$then \: force = mg = (2.5)(10)$

$force = 25$

let force be F=25N

Base area = 10^5 cm^2=10^5/10^4 m^2=10m^2

as 1cm=1/100 or 1/10^2m

$pressure = \frac{force}{area}$

Pressure=25/10=2.5 pa
