In Experiment $2,$ if the width of the quadrant $(w)$ is $75$ mm $,$ the water level in the

quadrant $(h)$ is $60$ mm $,$ the density of water $()$ is $1000k\frac{g}{m^3},$ the theoretical

hydrostatic force $(F_{th})$ is approximately:

$2\mathrm{.}3$ N

$1\mathrm{.}5$ N

$1\mathrm{.}7$ N

$1\mathrm{.}3$ N In Experiment $2,$ if the weight added to the tray is $1$ N $,$ the measured distance of the

weight tray from the pivot point $(I_W)$ is $175$ mm $,$ The theoretical hydrostatic force

$(F_{th})$ is $1\mathrm{.}5$ N $,$ the experimental distance of the hydrostatic force from Pivot point $(l_{ex})$

is approximately:

$75$ mm

$117$ mm

$233$ mm

$175$ mm
