Question

What is the resultant force on one side of a 25cm diameter circular plate standing at the bottom of 3m of pool water?

Answer 1

F=1.47 KN

Step-by-step explanation:

Given that

Diameter of plate = 25 cm

Height of pool h = 3 m

We know that force can be given as

F= P x A

P=ρ x g x h

Now by putting the values

P=1000 x 10 x 3

P= 30 KPa

`A=(\pi)/(4)* 0.25^2\ m^2`

`A=0.049\ m^2`

F= 30 x 0.049 KN

F=1.47 KN

So the force on the plate will be 1.47 KN.
