An L-shaped glass tube is just immersed in flowing water such that its opening is pointing against flowing water. If the speed of water current is v " id="MathJax-Element-147-Frame" role="presentation" style="position: relative;" tabindex="0">v " id="MathJax-Element-61-Frame" role="presentation" style="position: relative;" tabindex="0">v
, then :
1
The water in the tube rises to height \(\dfrac{v^{2}}{2g}\)
2
The water in the tube rises to height \(\dfrac{g}{2v^{2}}\)
3
The water in the tube does not rise at all
4
None of these.
