Question

4.A pressure of 1000 Pa is required to pierce a wooden block. If a sharp nail of area 0.1 cm is used,calculate the force required to pierce the wood.​

Answer 1

Answer:

100N

pressure=Thrust/area

1000=Thrust/0.1

Thrust=100N

Answer 2

Answer:

Given :

• Pressure = 1000 Pacsal

• Area = 0.1 cm²

• Force Required = ?

$\underline{\bigstar\:\textsf{According to the given Question :}}$

$:\implies\sf Pressure=\dfrac{Force}{Area}\\\\\\:\implies\sf 1000\:Pascal=\dfrac{Force}{0.1\:cm^2}\\\\\\:\implies\sf 1000\:N\:m^{-2} \times 0.1\:cm^2 = Force\\\\\\:\implies\sf 1000\:N\:m^{-2} \times \dfrac{0.1}{100 \times 100}\:m^2 = Force\\\\\\:\implies\sf \dfrac{0.1}{10} \:N = Force\\\\\\:\implies \underline{ \boxed{\sf Force =0.01 \:N}}$
