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