A) 200cm/s
B) 10cm/s
C) 25 cm/s
D) 50 cm/s
Correct Answer: A
Solution :
Key Idea: The standard equation to wave is \[\Rightarrow \] ??.(1) Where \[{{v}^{2}}=2gh\] is angular velocity, t is time. Given equation is \[=\sqrt{5g\frac{D}{2}}\] ??...(2) Comparing the given equation with standard wave form, we get \[\therefore \] and \[\sqrt{2gh}=\sqrt{5g\frac{D}{2}}\] Thus, velocity \[\Rightarrow \]
