SATHEE: Properties Of Solids And Liquids Question 255

Properties Of Solids And Liquids Question 255

Question: A $U$ -tube containing a liquid is accelerated horizontally with a constant acceleration a. If the separation between the two vertical limbs is $l$ , then the difference in the heights of the liquid in the two arms is

Options:

A) Zero

B) $l$

C) $\frac{l a}{g}$

D) $\frac{l a}{a}$

Show Answer

Answer:

Correct Answer: C

Solution:

[c] We know; $\tan θ = \frac{a}{g}$

In the present problem, $\tan θ = \frac{h}{l}$

So $\frac{h}{l} = \frac{a}{g}$

or $h = \frac{a l}{g}$ (Where h is the difference in the heights in the two limbs)
