A closed rectangular tank $5$m high, $3$m in width and $6$m in length is filled with $3\mathrm{.}5$m of water. If it is accelerated at $9$ m$/$s$^2$ determine the force experience at the both sides of the tank:

$(12)$ force acting on the left side

A$.292\mathrm{.}994$ kN

B$.301\mathrm{.}215$ kN

C$.410\mathrm{.}214$ kN

D$.579\mathrm{.}918$ kN

$(13)$ force acting on the right side

A$.8\mathrm{.}478$ kN

B$.6\mathrm{.}060$ kN

C$.12\mathrm{.}9$ kN

D$.23\mathrm{.}141$ kN

$(14)$ Force applied externally

A$.435\mathrm{.}651$ kN

B$.567\mathrm{.}018$ kN

C$.602\mathrm{.}135$ kN

D$.425\mathrm{.}517$ kN
