Question

A rectangular tank of $6m$ long, $2m$ broad and $2m$ deep is full of water, what is the thrust acting on the bottom of the tank?

• A. $23.52\times {10}^{4}N$
• B. $23.52N$
• C. $11.76\times {10}^{4}N$
• D. $3.92\times {10}^{4}N$

Answer 1

The correct option is A $23.52\times {10}^{4}N$

Volume of tank = $6\times 2\times 2m^3=24m^3$

of mass of water = $1000\frac{kg}{m^3}\times {24m}^3$

= 24000 kg

So Thrust = $24000\times 9.8N$

= 23.52$\times {10}^{4}N$
