A) 6m & 3m
B) 4m & 2m
C) 6m & 2m
D) 4m & 1m
Correct Answer: D
Solution :
Let t be the time interval between the drops. \[3t=1.34\Rightarrow t=0.44\sec .\] For second drop, h \[\frac{1}{2}\]x10x0.88x0.88=4.05 m. For third drop :h\[\frac{1}{2}\]x10x0.4x0.4= 1.05m.You need to login to perform this action.
