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{la}{g} $
D) $ \frac{la}{a} $
Show Answer
Answer:
Correct Answer: C
Solution:
[c] We know; $ \tan \theta =\frac{a}{g} $
In the present problem, $ \tan \theta =\frac{h}{l} $
So $ \frac{h}{l}=\frac{a}{g} $
or $ h=\frac{al}{g} $ (Where h is the difference in the heights in the two limbs)
