Question

Calculate the pressure produced by a force of 800N acting on an area of 20m²?​

Answer 1

ɢɪᴠᴇɴ :-

• Force (F) = 800N
• Area (A) = 20m²

ᴛᴏ ғɪɴᴅ :-

• Pressure (P)

Sᴏʟᴜᴛɪᴏɴ :-

We know that ,

→ Pressure = Force/Area

→ Pressure = 800/20

→ Pressure = 80/2

→ Pressure = 40 N/m²

Hence,

• Pressure produced = 40N/m²

Pressure—the effect of a force applied to a surface—is a derived unit, obtained from combining base units. The unit of pressure in the SI system is the pascal (Pa), defined as a force of one Newton per square meter. 



${ \boxed{ \boxed{ \purple{ \sf{ \: \: \: Pressure = \frac{Force}{Area} \: \: }}}}}$



${ \dagger{ \bold{ \green{ \: \: \: GIVEN }}}}$



${ \blue{ \sf{ Force \: = \: 800 \: N}}} \\ \\ { \blue{ \sf{Area \: = 20 \: {m}^{2} }}}$




⛦ substituting the given values in the formula...



${ \red{ \sf{ Pressure = \frac{800 \: N}{20 \: {m}^{2} } }}}$




${ \implies{ \red{ \sf{Pressure = 40 \: N \: {m}^{ - 2} }}}}$
