A body falls freely from the top of a tower. It covers 
of the total height in the last
second before striking the ground level. The height of the tower is
Text Solution
Verified by ExpertsThe correct answer is:
D
Let height of the tower be 
and body takes 
time to reach to the ground when it fall freely.
… (i)
In last second, i.e. 
th second, body travels 
It means in rest of time, i.e. in ( 
) seconds, it travels
Now, applying the Eq. of motion for 
seconds,
… (ii)
From Eqs. (i) and (ii), we get
