Length of horizontal arm of a uniform cross-section U-tube is l = 21cm and ends of both of the vertical arms are open to surrounding of pressure 10500 N/m2. A liquid of density is poured into the tube such that liquid just fills the horizontal part of the tube. Now one of the open ends is sealed and the tube is then rotated about a vertical axis passing through the other vertical arm with angular velocity  If length of each vertical arm be a = 6cm. Calculate the length of air column in the sealed arm in cm. [g = 10 m/sec2]
    Correct answer is '5'. Can you explain this answer?
    Verified Answer
    Length of horizontal arm of a uniform cross-sectionU-tube isl= 21cmand...
    Due to rotation, Let the shift of liquid is x cm.
    Let cross-section area of tube = A
    In the right limb for compressed air
    Force at the corner C of right limb climb due to liquid above.
    Mass of the liquid in horizontal arm
    It is rotated about left limb, then centripetal force
    But F1 = F2
    On solving x = 1 cm
    then length of air column = 6 – 1 = 5 cm
    The correct answer is: 5
