A tube is filled with a liquid as shown in figure. Then –
A
Liquid will spill out left tube if the tube is accelerated towards right horizontal direction with a > g/2
B
Liquid will spill out right tube if tube is rotated about left arm with angular velocity W > 
C
Liquid will not spill out the tube if it is rotated about axis AA ′ no matter what angular speed is
D
Liquid will spill out the tube if it is rotated about axis BB ′ with angular velocityꞷ> 
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a, b, c)
Figure ‘1’ shows condition of just spilling out of liquid, when tube is accelerated horizontally.
tan θ = 
= 
Also, tan θ = 
[a = acceleration of U tube]
⇒ a = g/2
Figure 2 Shows condition of just spilling out of water its rotated about left arm.
At x = 4b
y = 2b
Putting value in y = 
.x 2
2b = 
.(4b) 2
ꞷ =
