Question

A force of 20 N acts on a surface of area 70 cm².calculate the pressure exerted on the surface. into pascal

















​

Answer 1

F = 20N

ar. of surface, A = 70cm² = 0.007m²

Pressure = F/A = 20/0.007 Pa = 2847.14 Pa

Answer 2

Explanation:

$\huge\underline\mathfrak{Answer}$

GIVEN

force = 20N

area = 70cm^2

First we should convert 70cm^2 into m^2

We know that 1 cm^2 = 10^-4 m^2

So,

70 cm^2 = 70 × 10^-4 m^2

= 1/7000 m^2

TO FIND

Pressure on the body

We know that,

pressure = force/area

= 20/1/7000

= 20 × 7000

= 140000

$= 140000 {ms}^{ - 2}$
