Question

a body weighed 30kg is placed on the square surface of 10m length . Calculate the pressure applied to the surface assuming the value of acceleration due to gravity 10m/s2

Answer 1

Answer:

3 pascal

Explanation:

$\sf{\underline{\bigstar\:Given:}}$

• Mass (m) = 30 kg
• Length of side of square surface (a) = 10 meter
• Acc due to gravity (g) = 10 m/s²

$\sf{\underline{\bigstar\:To\:find:}}$

• Pressure applied (P) = ?

$\sf{\underline{\bigstar\:Solution:}}$

We know that, $\sf{\blue{Pressure(P)\:=\:\dfrac{Force(F)}{Area(A)}}}$

Where, Force = mass(m) × acceleration due to gravity(g)

(Let's first find force and then pressure! )

$\longrightarrow$ F = 30 × 10

$\longrightarrow\:\sf{\boxed{Force\:=\:300\:Newton}}$

Now, we know that area of square = (side)²

$\longrightarrow$ Area of square = (10)²

$\longrightarrow\:\sf{\small{\boxed{Area\:=\:100\:m^2}}}$

Now finally put all the values in the formula of pressure !

$\longrightarrow\:\sf{P\:=\:\dfrac{300}{100}}$

$\longrightarrow\sf{\green{\small{\boxed{Pressure\:=\:3\:Pa}}}}$
