Which of the following is not possible?
Open in App
Solution
The correct option is D
The pressure at any point can never have different value.
Option a) Pressure at (A) due to both limbs is different, as liquids of different density at same height are present. Hence not possible.
Option d) Pressure at (D) due to both limbs is different, as liquid at different heights are present. Hence not possible.
Hence (A) and (D) are not possible.
In case of insufficient length of capillary tube the shape of meniscus is as below:
Why this Question?
Pascal’s principle, an experimentally verified fact, is what makes pressure so important in fluids.
