Question

A vessel of base area 100cm * 60 cm and height 200 cm is completely filled with a liquid of density $1.1\times {10}^{3}kg/m^3$. Find the thrust a the bottom of the vessel ignoring the atmospheric pressure.

• A. $1.294\times {10}^4$
• B. $1.294\times {10}^3$
• C. $1.294\times {10}^5$
• D. $1.294\times {10}^2$

Answer 1

The correct option is A

$1.294\times {10}^4$

Area of the base of the vessel = 100 cm * 60 cm = $0.6m^2$

Volume of the vessel = 100 cm * 60 cm * 200 cm

= $1.2m^2$

Thrust at the bottom of the vessel = weight of liquid in the vessel = volume * density

= $1.2\times (1.1\times {10}^3)\times 9.8$

= $1.294\times {10}^4$
