Question

a box that feat 500 N
and is at rest on the floor if the pressure exerted by the box on the floor is 20000 Anam to over what year is area is the box in contact with the floor​

Answer 1

Correct QuEstion: A box that feels a force 500 N and is at rest on the floor if the pressure exerted by the box on the floor is 20000 Pa. Then what is the area, the box is in contact with the floor.

ProvidEd that:

• Force = 500 N
• Pressure = 20000 Pa

To calculaTe:

• Area

SoluTion:

• Area = 0.025 metre sq.

UsiNg concept:

• Pressure formula

UsiNg formula:

• ${\small{\underline{\boxed{\pmb{\sf{Pressure \: = \dfrac{Force}{Area}}}}}}}$

RequirEd solution:

$:\implies \sf Pressure \: = \dfrac{Force}{Area} \\ \\ :\implies \sf 20000 = \dfrac{500}{Area} \\ \\ :\implies \sf Area \: = \dfrac{500}{20000} \\ \\ :\implies \sf Area \: = \dfrac{5}{200} \\ \\ :\implies \sf Area \: = \dfrac{1}{40} \\ \\ :\implies \sf Area \: = 0.025 \: m^2$

Answer 2

Given:

Weight of the box = 200 N (i.e, the force exerted by the box)

Pressure exerted by the box = 20,000 Pa (Pascal)

To find:

Contact Area of the box with the floor

Method to find:

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

$⇒ \: 20,000 \ = \sf \frac{200}{area}$

$⇒ \bf \ Area \ = \frac{200}{20,000}$

$\bf⇒ Area = 0.01 m²$

━━━━━━━━━━━━━━━━━━━━━━

Hence, the box is in contact with 0.01 m² of the floor
