Question

A roof has a surface area of 20000,if the atmospheric pressure exerted on the roof is 100000,dertimine the force on it (take 10Nkg1)
Thank

Answer 1

Answer:

2000N

Explanation:

Given- Pressure= 1,00,000 Pa.

Area= 20,000 cm square.

Formula used- P=\frac{F}{A}P=

A

F

Now,

Convert the units.

1 m = 100 cm.

20,000 cm square=0.02 m square.

1,00,000=F/0.02

Therefore, F=2000N

Answer 2

Answer:

2000 N.

Explanation:

Given- Pressure= 1,00,000 Pa.

            Area= 20,000 cm square.

Formula used- P=\frac{F}{A}P=AF

Now,

Convert the units.

1 m = 100 cm.

20,000 cm square=0.02 m square.

1,00,000=F/0.02

Therefore, F=2000N
