Repeat the process above, but this time, use it to estimate the location of the hydrostatic force as follows:

a$.$ Determine the hydrostatic force theoretically, $F_{th}.$ Here, you'll need to use your measured width

of the container $()$

$F_{th}=\frac{1}{2}g{h}^2$

b$.$ Using your measured weight $W,$ and measured distance to the pivot point $l_W,$ perform a

moment balance $({\displaystyle \underset{?}{\overset{?}{}}}M=0)$ about the pivot point and solve for the experimental location of the

hydrostatic force, $l_{ex}$

$F_{th}{l}_{ex}=W{l}_W$
