Question

A block of length 20m and width 10m, lying on the ground exerts a force of 400N on the ground. The pressure exerted by the block is​

Answer 1

Answer -

• The pressure exerted by the block = 2N/m².

To calculate -

• The pressure exerted by the block.

Step-by-step explanation -

• Here, the dimensions of a block and the force exerted on it are given to us. We have to find the pressure exerted by this block. For that, we first need to find it's area!

We know that -

$\bigstar \: \underline{\boxed{\sf Area_{(rectangle)} = Length \times Breadth}}$

Here -

• Length = 20 m.
• Breadth = 10 m.

Therefore -

$\mapsto \rm Area \: of \: the \: block = 20 \times 10$

$\mapsto \rm Area \: of \: the \: block = 200 \: m^2$

• Now, let's calculate the pressure exerted by the block!

We know that -

$\bigstar \: \underline{\boxed{\sf Pressure = \dfrac{Force}{Area}}}$

Here -

• Force = 400N.
• Area = 200 m².

Therefore -

$\bf\longmapsto \: Pressure = \cancel{\dfrac{400}{200}}$

$\bf\longmapsto \: Pressure = 2N/m^2$

Hence -

• The pressure exerted on the block = 2N/m².
