Question

A solid weighs 300N. Calculate the pressure exerted by the solid on a surface, if the area of contact is 20cm x 20cm

Answer 1

Answer:

3/4

Explanation:

P=F/A , area= 20x20cm = 400cm² and we can take the force as the weight of the solid object. So F= 300N

P= 300N/400cm²

so P= 3/4Ncm-²

Answer 2

Answer:

$pressure \: = \frac{force}{area} \\ = \frac{300}{20 \times 20} \\ = \frac{3}{4}$

Explanation:

3/4 Pa
