Question

22.
Imagine a girl of mass 50 kg standing on pencil heels, each of area of cross-section of 1cm square, and an elephant of mass 2000 kg and foot area of 250 cm square standing on floor. Find the
pressure exerted by each of them assuming acceleration due to gravity is 10 m/s square. Which of the two exerts more pressure on the floor? the correct answer with correct process will be chosen as brainlist answer.

Answer 1

$\huge{\mathfrak{Answer:-}}$

Girl

Mass - 50 kg

Area - 1 cm² = 0.0001 m²

Hence,

Force = Mass × Acceleration

Hence,

Force = 50 × 10

Force = 500 N

As we know,

$\red{Pressure={\frac{Force}{Area}}}$

Now, we get

Pressure = $\frac{500}{0.0001}$

Hence, Pressure exerted = 50,00,000 N/m²

ELEPHANT

Mass - 2000 kg

Area - 250 cm² = 0.025 m²

Force = Mass × Acceleration

Hence,

Force = 2,000 × 10 = 20,000

As we know,

$\blue{Pressure = {\frac{Force}{Area}}}$

Now, we get

Pressure = $\frac{20,000}{0.025}$

Hence, pressure exerted = 8,00,000 N/m²

Hence, more pressure is exerted by the girl in heels✌
