Question

Solve the numerical given below :. Force=4 Newton ; area =16cm ‌‌‌‌‌‌‌square; pressure=?

Answer 1

$\blue{\bold{\underline{\underline{Answer:}}}}$

$\green{\therefore{\text{Pressure}}=2.5\times10^{3}N/m^{2}}$

$\orange{\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

$\green{ \underline \bold{Given :}} \\ : \implies \text{Force = 4 \: N} \\ \\ : \implies \text{Area = 16 \: cm}^{2} \\ \\ \red{ \underline \bold{To \: Find :}} \\ : \implies \text{Pressure = ?}$

• According to given question :

$\bold{According \: to \: formula \: of \: pressure : } \\ : \implies \text{Pressure = force \: per \: unit \: area} \\ \\ : \implies \text{Pressure }= \frac{Force}{Area} \\ \\ \bold{\circ \: \: area = 16 {cm}^{2} = 0.0016m^{2} = 16 \times {10}^{ - 4} } \\ \\ : \implies \text{Pressure } = \frac{4}{16 \times {10}^{ - 4} } \\ \\ : \implies \text{Pressure }= \frac{10 ^{ 4} }{4} \\ \\ \green{: \implies \text{Pressure =} 2.5 \times {10}^{3} \: N/{m}^{2}}$

Answer 2

Explanation:

pressure = Force/ Area

pressure = 4/(16 × 10^{-4})

pressure = 2.5 × 10^{-3}
