Question

If a force of 154 N is applied on a circular surface of radius 14m then find the pressure so exerted.​

Answer 1

ɢɪᴠᴇɴ :-

• Force(F) = 154 N
• Radius(r) of circular surface = 14 m

Tᴏ ғɪɴᴅ :-

• Pressure(P)

sᴏʟᴜᴛɪᴏɴ :-

Now,

We know that,

➦ Area of Circle = πr²

➮ πr² = 22/7 × 14 × 14

➮ 22 × 2 × 14

➮ 44 × 14

➮ 616cm²

Hence,

➦ Area of circular surface = 616 m²

Now,

We know that,

$\implies \: \sf Pressure(P) = \frac{Force(F)}{Area(A)} \\ \\ \implies \: \sf P = \frac{F}{A}$

On putting above values in it, we get,

$\implies \: \sf P = \frac{154}{616} \\ \\ \implies \: \sf P = 0.25$

Hence,

• Pressure (P) = 0.25 N/m² or Pascal

✰Question ✰

⋄ If a force of 154 N is applied on a circular surface of radius 14m then find the pressure so exerted?

_______________________________

❍ Given :-

⋄ Force (F) =154 N

⋄ Radius of Circular surface (r) =14 m

_______________________________

❍ To Find :-

⋄Pressure (P)

_______________________________

❍ Solution :-

we know that,

⋄ Area of Circle =πr²

➧ Area of circle =22/7×14 ×14

➧ Area of circle = 616m²

∴Area of circular surface =616m²

Now,

Pressure = Force/Area

➧ P=F/A

➧ P = 154/616

➧ P=0.25Pascal

∴The pressure exerted on circular surface is 0.25 Pascal.
