A) \[{{h}_{1}}:{{h}_{2}}\]
B) \[\sqrt{{{h}_{1}}}:\sqrt{{{h}_{2}}}\]
C) \[{{h}_{1}}:2{{h}_{2}}\]
D) \[2{{h}_{1}}:{{h}_{2}}\]
Correct Answer: B
Solution :
According to second equation of motion \[h=\frac{1}{2}g{{t}^{2}}\] \[\therefore \] \[\frac{{{t}_{1}}}{{{t}_{2}}}=\sqrt{{{h}_{1}}}:\sqrt{{{h}_{2}}}\]You need to login to perform this action.
