Question

A man applies a pressure of 3N/m2 to jump over a wall. Calculate the force applied by him if the surface area of wall is 1m2 .​

Answer 1

Answer:

3 N

Explanation:

As per the provided information in the given question, we've been given the magnitude of pressure and area. We've been asked to calculate the force applied.

We have,

• Pressure (P) = 3 N/m²
• Area (A) = 1 m²

We have to calculate the force applied. As we know that,

$\longrightarrow \sf{\quad {P = \dfrac{F}{A} }}$

• P denotes pressure
• F denotes force
• A denotes area

Substitute the values in the formula.

$\longrightarrow \sf{\quad {3 = \dfrac{F}{1} }}$

$\longrightarrow \sf{\quad {(3 \times 1) \; N= F }}$

$\longrightarrow \quad \underline{\boxed{ \textbf{\textsf{ 3 \; N = F }}}}$

Therefore, force applied is 3 N.

• Pressure is defined as force per unit area.
• Its SI unit is Pa.
• Pa is equivalent to N/m².
• Force is defined as push or pull which tends the position, shape, speed of the object.
• SI unit of force is Newton.
• Newton is denoted by N.
• Force is also the product of mass and acceleration, i.e Force = Mass × Acceleration
