Question

A tank 5 m high is half filled with water and then is filled to the top with oil of density 0.85 g/cm³. The pressure at the bottom of the tank, due to these liquids is

• A. 1.85 g/cm²
• B. 89.25 g/cm²
• C. 462.5 g/cm²
• D. 500 g/cm²

Answer 1

Answer: (C)

462.5 g/cm²

Answer 2

Pressure at the bottom

$= [ 250 \times 1 + 250 \times 0.85 ] = 250 [ 1.85 ] \frac { \mathrm { g } } { \mathrm { cm } ^ { 2 } }$

$= 462.5 \frac { \mathrm {~g} } { \mathrm {~cm} ^ { 2 } }$
