Question

Calculate the pressure exerted by a person
weighing 600 N when she is:
(i)Standing on her feet, with area of
contact between each foot and floor
being 0.0015 m.
(ii) Sitting on a chair with total area of
contact on the chair being 0.01 m²​

Answer 1

Answer:

Explanation:

Pressure =force/Area

(1) force =600N

Area = 0.0015m

Now pressure = 600/0.0015=4,00,000

(2)Area = 0.01m²

Hence pressure= 600/(0.01*0.01)=6,000,000
