Question

a solid cube of area 25m^2 and weighing 625N is placed on a table calculate the preson

Answer 1

Answer

Pressure = 25 Pascals

Given

A solid cube of area 25 m² and weighing 625 N is placed on a table

To Find

Pressure

Solution

We know that , " Pressure  is defined as force acting per unit area "

$\implies \bf P=\dfrac{F}{A}\ \;\; \bigstar$

Area , A = 25 m²

Weight = Force , F = 625 N

Pressure , P = ? N/m²

$\implies \rm P=\dfrac{F}{A}\\\\\implies \rm P=\dfrac{625}{25}\\\\\implies \rm P=\dfrac{25\times 25}{25}\\\\\implies \rm P=25\ N/m^2\\\\\implies \rm P=25\ Pa$

More Info

SI unit of Pressure is Pascal

SI unit of Force is Newton

SI unit of Area is m²

Answer 2

Given

• Force = 625 N

• 625 NArea = 25 m²

To Find

• Pressure

Pressure = ᶠᵒʳᶜᵉ⁄ₐᵣₑₐ

➯ ⁶²⁵⁄₂₅

➯ 25

Therefore, Pressure = 25 Pascal

Additional Information

Force per unit area is called pressure.

Push or Pull is termed as a Force.

• Pascal is the SI unit of Pressure
• Newton is the SI unit of Force
• Meter is the SI unit of Area

Important Formulas

• Force = Mass × Acceleration
• v = u + at
• S = ut + 1/2at²
• v² - u² = 2as
