Question

A tank 5 m high is half filled with water and then is filled to the top with oil of density $0.85g/c{m}^3$. The pressure at the bottom of the tank, due to these liquids is

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

Pressure at the bottom $P=(h_1{d}_1+h_2{d}_2)\frac{g}{c{m}^2}=[250\times 1+250\times 0.85]=250\left[1.85\right]\frac{g}{c{m}^2}=462.5\frac{g}{c{m}^2}$
