An L-shaped glass tube is immersed in a flowing liquid such that its opening is pointing against the currents. If the speed of flow is `v`

Study following statement:
(i) the liquid in the tube rises to a level `A`
(ii) The liquid in the tube rises to the level `B`
(iii) The liquid in the tube rises to the level `C`
(iv) The magnitude of `h` is `(v^2)/(2g)`
Choose the correct statement (s)

Options

A. (i) & (ii)
B. (ii) & (iv)
C. (iii) & (iv)
D. (i) & (iii)

Answer

B

Explanation

Applying Bernoulli's equation, we find that water rises to a height `h=v^(2)//2g`.
