Question

The depth of the dam is 240 m. The pressure of water is (Take $g=10m/s^2$ density of liquid = $1000kg/m^3)$

• A. $24\times {10}^{5}N/m^2$
• B. $12\times {10}^{4}N/m^2$
• C. $10\times {10}^{3}N/m^2$
• D. None of these

Answer 1

The correct option is A $24\times {10}^{5}N/m^2$

Pressure of water at height H is given by :

$P=\rho gH$

Here $\rho =1000kg/m^3$ $g=10m/s^2$ and $H=240m$

Putting all values we get

$P=1000\times 10\times 240=24\times {10}^{5}N/m^2$

Option A is correct.
