A stone drop from height `h` reaches to earth surface in 1 sec. if the same stone taken to moon and drop freely then it will reaches from the surface of the moon in the time (the 'g' of moon is 1/6 times of earth)-

`sqrt(6)` second

9 second

`sqrt(3)` second

6 second

Text Solution

Verified by Experts

The correct Answer is:

`t=sqrt((2h)/(g))=1` sec, `t'=sqrt((2h)/(g))=sqrt(6)sqrt((2h)/(9))=sqrt(6)sec`
