Question

A force of 400 N acts on an area of 0.04 meter square then the pressure exerted is

Answer 1

Answer :-

P = 10,000 p

Given:-

F = 400 N

A = 0.04 m²

To find :-

The pressure exerted.

Solution:-

Pressure :- The force exerted per unit area of a surface is known as pressure.

The force exerted per unit area of a surface is known as pressure. It's SI unit is pascal.

From definition we have,

$\boxed{\sf{ P = \dfrac {F}{A}}}$

put the given value,

$\implies$ $P = \dfrac {400}{0.04}$

$\implies$ $P = 10,000p$

hence, pressure exerted by force will be 10,000 p.

Answer 2

Answer:

1. p=F/a=p=10000=10⁴pa or 10⁵cm²or nm2
