Question

A body of area 10 cm ×5 cm exerts a force of 30 Newton the pressure will be

Answer 1

Given:-

• Area = 10×5

• Force = 30 N

To Find:-

• Pressure on the body ,p

Solution:-

Firstly we convert the unit here

Area = 10cm×5cm

Area = 50cm²

1m² = 10000cm²

∴ 50cm² = 50/10000 = 0.005 m²

Now we know that

→ Pressure = Force/Area

→ p = F/a

Substitute the value we get

→ p = 30/0.005

→ p = 30×1000/5

→ p = 6×1000

→ p = 6000 Pa

∴ The pressure acting on the body is 6000 Pascal.

Answer 2

Given :-

• Area = 10 × 5
• Force = 30N

To Find :-

• Pressure on the body.

Solution :-

Firstly,

• Area = 10cm × 5cm

• Area = 50cm²

• 1m² = 10000m²

• 50cm² = $\rm\dfrac{50}{10000} {m}^{2}$ = 0.005m²

Now,

• Pressure = $\rm\dfrac{Force}{Area}$

Substitute,

• $\rm{p = \dfrac{30}{0.005} {m}^{2} }$

• $\rm{p = 30 \times \dfrac{1000}{50} }$

• $\rm{p = 6 \times 1000}$

• $\rm{p = 6000Pa}$

$\therefore$ The pressure on the body is 6000Pascal.
