Question

A statue has a base which is 20cm×20cm in dimension and exerts a pressure of 1000N/m^2.what is its weight​

Answer 1

Answer:

First of all force = weight so

we have 20$cm{2}$ and 1000Pascal which is pressure so

first let us convert 20$cm{2}$ in m so it is  0.002$m{2}$

force = area × pressure so  

0.002 × 1000 = 2

so the weight is 2Newtons which actually force

Answer 2

Given,

Amount of exerted pressure by the statue = 1000 N/m²

Dimensions of the base of the statue = 20 cm × 20 cm

To find,

The weight of the statue.

Solution,

We can simply solve this numerical problem by using the following process.

Dimensions of the base of the statue in SI units :

= 0.2 m × 0.2 m

(Term of unit conversion : 100 cm = 1 m)

So, Area of the base :

= (0.2 × 0.2) m²

= 0.04 m²

Now, according to the mathematical relationship between force, area and pressure, we get -

Pressure = Force / Area

1000 = Force / 0.04

Force = (1000 × 0.04) N

So, Force = 40 N

Here,

The force exerted by the statue = The weight of the statue = 40 N

Hence, the weight of the statue is 40 N
