Question

find the pressure exerted on the floor by a 1ooN box whose bottom area 0.2m/2(use pa for unit)

Answer 1

Answer:

The pressure exerted on the floor by a 100 N box whose bottom area 0.2m/2 is 500 Pa.

Explanation:

Given,

Force = 100 N

Area = 0.2 m/2

Pressure = ?

To find:

Pressure = $\frac{Force}{Area}$

Pressure = $\frac{100}{0.2}$

Therefore, Pressure = 500 Pa.

Pressure:

Pressure is the thrust per unit area of surface.

Pressure is a scalar quantity.

The SI unit of pressure is newton per metre² which is abbreviated as N m/2.

This unit is named pascal (symbol Pa) after the name of the French scientist Blaise Pascal.

Answer 2

Find the pressure exerted on the floor by a hundred N box bottom area 0.2 m/2 ( use pa for unit)

${ \huge{ \bold{\underline{ \underline{ \orange{♡AnSWer♡}}}}}}$

$\star{\sf{\underline{\green{\: step \:by \: step\: explanation:-}}}}$

We know,

ꔷ Force = 100N

ꔷArea = 0.2m/2

ꔷ Pressure = ?

$\star{\bf{\underline{\green{\: Formula \: used:-}}}}$

$\mapsto\boxed{\tt{\red{P = \frac{F}{A}}}}$

NoW,

$\implies{\tt{\blue{p = \frac{F}{A}}}}$

$\implies{\tt{\blue{p = \frac{100}{0.2}}}}$

$\implies{\tt{\blue{p = 500}}}$

$\implies{\tt{\blue{Hence\:, the\: pressure\: = 500 pa}}}$

♡ Pressure ♡:-

★The pressure at a point due to a fluid is the normal force exerted by the fluid on unit area containing the point .

★Pressure is a scalar quantity as it has no directional property while trust is a vector quantity .

★ The SI unit CGS units of pressure and newton per square metre and time for square centimetre . The SI unit of the pressure is also called the Pascal.

Thus 1 pa = 1 Nm^-2
