The curved wall of a dam is described by the equation
`x^(2) = 2y`
The coordinates of point A are (4m,8m) . The width of the dam is 2m and the fluid is water of density ` 1xx10^(3) kg//m^(3)`
Atmospheric pressure is ` 1.0 xx 10^(5)` Pa

The horizontal component of the force applied by the liquid on the surface AB is `(g = 10 ms^(-2))`

Options

A. `4.3 xx 10^(5)N`
B. `6.4 xx10^(5)N`
C. `7.2 xx10^(5)`N
D. `22.4 xx10^(5)`N

Answer

D
