Question

a force of 20 Newton acts on a surface of area 70 cm square calculate the pressure exerted on the surface​

Answer 1

Answer:

Explanation:$\huge\bold\tt{answer}$

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

Answer 2

Answer:

p=f/a. 20/(70/10000) = 2857. l Pascal
