Question

Calculate the pressure exerted by a block of weight 500N if the surface area in contact is 2.5cm square

Answer 1

we will convert 2.5cm square to meter square= 0.00025

force=500N
area=0.00025m square

pressure=force/area = 500N / 0.00025m square 
                                      = 2000000 pascal

Answer 2

Given:

Block's weight,

= 500 N

Surface area,

= 2.5 cm²

or,

= 0.00025 m²

To find:

Pressure = ?

Solution:

As we know,

⇒ $Pressure=\frac{Force}{Area}$

By substituting the values, we get

⇒                 $=\frac{500}{0.00025}$

⇒                 $=2000000 \ pascal$

Thus, the pressure will be "2000000 pascal".
