Question

There are two fish tanks each of depth $0.5\text{m}$ filled upto the brim. Base area of one is $0.5{\text{m}}^2$ and that of another is $0.1{\text{m}}^2$. At the depth of which tank will a fish feel larger pressure?

• A. The tank of wider base area
• B. The tank of smaller base area
• C. Equal for both tanks
• D. Can't say

Answer 1

The correct option is C Equal for both tanks

Liquid pressure is given by $=\rho \times g\times h$
So, liquid pressure depends on the depth and not on the base area.
Here, both the tanks have the same depth. So, in both the tanks, the fish will feel equal pressure.
