A) \[\sqrt{2}s\]
B) \[2\pi \sqrt{2}s\]
C) \[2s\]
D) \[2\sqrt{2}s\]
Correct Answer: D
Solution :
Velocity at point\[P=\sqrt{\frac{\frac{m}{L}gx}{m/L}}\]\[v=\sqrt{gx}\] \[\frac{dx}{dt}=\sqrt{gx}\] \[\int\limits_{0}^{20}{\frac{dx}{\sqrt{x}}=\int\limits_{0}^{t}{\sqrt{g}}dt}\] \[\]You need to login to perform this action.
