A given shaped glass tube having uniform cross section is filled with water and is mounted on a rotatable shaft as shown in figure. If the tube is rotated with a constant angular velocity $\omega $then
Water levels in both sections $A$ and $B$ go up
Water level in Section $A$ goes up and that in $B$ comes down
Water level in Section $A$ comes down and that in $B$ it goes up
Water levels remains same in both sections
A container of mass $M$ containing liquid of mass $m_0$ is kept on weighing machine. A ball of mass $m$ is released from rest from given position. Then choose correct option just after ball is released
A tube is bent into $L$ shape and kept in a vertical plane. If these three liquids are kept in equilibrium by the piston of area $A$ , the value of $\frac {F}{A}$ is
In the arrangement shown both the vessels $A$ and $B$ are identical but amount of water in $B$ is double of that in $A$. The vessels are closed by identical leak proof pistons at the same height. The pistons are connected to the ends of lever arm. There is no friction between the pistons and the container walls. The system is in equilibrium in the situation shown. Now the valve in the horizontal tube connecting both the vessels is opened. In which direction will the water flow through the tube ?
A cylinder of radius $4\ cm$ and height $10\ cm$ is immersed in two liquids as shown. Specific gravity of oil is $0.5$ . $2\ cm$ of cylinder is in the air. Select the $INCORRECT$ statement. Neglect atmospheric pressure.
A vertical U-tube of uniform cross-section contains water in both the arms. A $10 \,cm$ glycerine column ($R.D$. $=1.2$ ) is added to one of the limbs. The level difference between the two free surfaces in the two limbs will be ...... $cm$
