A straight tube of length L contains incompressible liquid of mass M and the closed tube is whirled in horizontal plane about one of the ends. If ω ω is the uniform angular velocity, the force exerted by the liquid on the other end is
A
B
2ML ω ω 2
C
D
ML ω ω 2
Text Solution
Verified by ExpertsThe correct answer is:
A
Let there be a small element of length dl at a distance L from the end of rotational axis.
Mass of the element dl = 
dl
Small radial force on this element = 
l ω ω 2 ∴ ∴ Total force = 
=
