Question

answer this pliz im in a hurry​

Answer 1

Given:

Pressure exerted = 525 Pascal

Dimensions of box = 500 cm × 150 cm × 10 cm

To find:

Force exerted by box

Concept:

We have to consider three cases where different values of forces will be calculated based on the value of area upon which the force acts.

Calculation:

1st case :

Area = 500 × 150 = 75000 cm² = 7.5 m²

$\therefore$ Force = 7.5 × 525 = 3937.5 N

2nd case :

Area = 500 × 10 = 5000 cm² = 0.5 m²

$\therefore$ Force = 0.5 × 525 = 262.5 N

3rd case :

Area = 150 × 10 = 1500 cm² = 0.15 m²

$\therefore$ Force = 0.15 × 525 = 78.75 N

We have to follow this three cases because the question hasn't mentioned the area of cross-section upon which the object is placed on the sand.
