Question

a boy weighing 60kgf stands on platform of dimensions 2.5 cm x 0.5 cm . what pressure in pascal does he exert?

Answer 1

weight of boy = 60 kgf = 600 N
area of platform = 2.5cm × 0.5 cm
= 1.25 cm²
= 1.25 × 10-⁴ m²

Pressure exerts in platform = weight/area
= 600 N/1.25 × 10-⁴ m²
= 480 × 10⁴ N/m²
= 4.80 × 10⁶ N/m²

Answer 2

Answer:

Weight=60kgf

Area=2.5×0.5cm

1.25 cm^2

1.25×10^-4

Explanation:

We know

Pressure exerts in platform=w/a

600n/1.25×10^-4

480×10^4N/m^2

4.80×10^6N/m^2 is the answer
