A) \[{{\left[ \frac{2G}{r}{{m}_{1}}{{m}_{2}} \right]}^{1/2}}\]
B) \[(\Delta l)\]
C) \[50{{m}^{2}}/{{s}^{2}}\]
D) \[50.5{{m}^{2}}/{{s}^{2}}\]
Correct Answer: A
Solution :
Let A = cross-sectional of tank a = cross-section hole V = velocity with which level decreases v = velocity of efflux From equation of continuity, av = AV \[3{{R}^{2}}=\frac{5}{{{\omega }^{2}}{{C}^{2}}}\] \[\Rightarrow \] By using Bemoullis theorem for energy per unit volume. Energy per unit volume at point A = energy per unit volume at point B \[\frac{\frac{1}{\omega C}}{R}=\sqrt{\frac{3}{5}}\] \[\Rightarrow \] \[\frac{{{X}_{C}}}{R}=\sqrt{\frac{3}{5}}\] \[\lambda ={{\lambda }_{1}}+{{\lambda }_{2}}\]You need to login to perform this action.
