Question

A rock exerts 5000 Pa of pressure on the ground. If the rock weighs 250 N, how much area is in contact with the ground?

8 m2

50 m2

20 m2

0.05 m2

Answer 1

P = F/S - S = F/P = 250/5000= 0.05 m2

Answer 2

Answer:

Area=0.05 $m^{2}$

Explanation:

Given pressure=5000 Pa

and weight=250 N

Using equation

Pressure=Force/Area

So,Area=Force/pressure

Area=250/5000

Area=0.05 $m^{2}$
