A) \[\sqrt{\frac{g\left( {{H}^{2}}+{{L}^{2}} \right)}{2H}}\]
B) \[\sqrt{\frac{g{{H}^{2}}}{\sqrt{{{H}^{2}}+{{L}^{2}}}}}\]
C) \[\sqrt{\frac{g\sqrt{{{H}^{2}}+{{L}^{2}}}}{H}}\]
D) \[\sqrt{\frac{2g{{H}^{2}}}{\sqrt{{{H}^{2}}+{{L}^{2}}}}}\]
Correct Answer: A
Solution :
\[t=\frac{s}{v}=\sqrt{{{H}^{2}}+{{L}^{2}}}\div \sqrt{\frac{2H}{g}}\]You need to login to perform this action.
