A large aquarium of height 5.00 m is filled with fresh water to a depth of 2.00 m. One wall of the aquarium consists of thick pl

earnstyle [38]

Answer:

total force = 4.704 × $10^5$ N

Explanation:

given data

height = 5 m

depth = 2 m

thick plastic = 8.00 m

depth = 4.00 m

solution

first we get here force in which aquarium fill with depth 2 m

dF = PdA ......1

F = ∫PdA

F = ∫ϼgy(wdy)

F = ϼgw ∫ y dy

F = ϼgw × $\frac{y^2}{2}$ .................2

F = $1000 \times 9.8 \times 8 \times \frac{2^2}{2}$

F = 1.568 × $10^5$ N

and

now we get here force for depth 4 m

put here value in equation 2

F = $1000 \times 9.8 \times 8 \times \frac{4^2}{2}$

F = 6.272 × $10^5$ N

so that here

total force will be

total force = 6.272 × $10^5$ N - 1.568 × $10^5$ N

total force = 4.704 × $10^5$ N
