Question

Three liquids having densities $P_1,P_2$ and $P_3$ are filled in a U-tube. Length of each liquid column is equal to l, $P_1>P_2>P_3$ and liquids remain at rest (relative to the tube) in the position shown in the figure. It is possible that

• A. U - tube is accelerating leftwards
• B. U - tube is accelerating upwards with acceleration g
• C. U - tube is moving with a constant velocity
• D. none of the above

Answer 1

The correct option is D none of the above

$\text{The u-tube remain at rest because}3\text{liquids}$

$\text{arange them selps according to the atmospheric}$

$\text{Pressure by the way onty heights changes.}$

$\text{Answer: (D)}$
