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 remain same in both sections
A boat carrying a number of stones is floating in a water tank. If the stones are unloaded into water, the water level in the tank will ............
Application of Bernoulli's theorem can be seen in
A cylindrical vessel filled with water upto the height $H$ becomes empty in time $t_0$ due to a small hole at the bottom of the vessel. If water is filled to a height $4H$ it will flow out in time
There are two identical small holes of area of cross-section a on the opposite sides of a tank containing a liquid of density $\rho $. The difference in height between the holes is $h$. Tank is resting on a smooth horizontal surface. Horizontal force which will have to be applied on the tank to keep it in equilibrium is
In a $U-$ tube experiment, a column $AB$ of water is balanced by a column $‘CD’$ of oil, as shown in the figure. Then the relative density of oil is
