Question

We know Pressure = _______ Area
If 50 N force is applied on a liquid and it experiences 25 N/m2
pressure.
Find out the area on which the force is applied?

TNSCERT Class 8 Science Ch7. Force and Pressure

Answer 1

We know that 
Pressure = $\frac{Force}{Area}$ 
Further, here we have:
Pressure = 25 N/$m^{2}$ = 25 Pa 
Force  = 50 N
So, 
area = $\frac{Force}{Pressure}$
area = $\frac{50}{25}$
area  = 2 $m^{2}$

Answer 2

We know that pressure = $\frac{Force}{Area}$

given :
pressure = 25n/m²
force = 50 N

solution:
⇒ The area applied
changing the pressure into Pascal = 25 Pa

⇒ pressure = $\frac{Force}{Area}$
= area = $\frac{Force}{Pressure}$
⇒ area = 2m²
∴ The area on which the force is applied is 2m²
