Question

a boy weight 60kgf stands on a platform of dimension 2.5cm × 0.5cm. what pressure in pascal does he exert?

a. 4.8 ×10⁴ Pa

b. 4.8 × 10⁶ Pa

​

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

opioian b

Answer 2

Answer:

b 4.8×10⁰pa

Explanation:

600n/1.25×10=

480/10=4.8×10⁰pa
