Explanation:

when the 6th ball is being dropped.
5th ball has travelled for 1 sec
4th Ball for 2 sec
3rd Ball for 3 sec
S = ut +(1/2)at²
u = 0 dropped
a = g = 10 m/s²
t = 1 , 2 , 3
Distance Covered in 1 Sec = (1/2)10*1² = 5 m
Distance Covered in 2 Sec = (1/2)10*2² = 20 m
Distance Covered in 3 Sec = (1/2)10*3² = 45 m
the positions of the 3rd 4th and 5th ball are 45 m , 20 m & 5 m below the top of tower when 6th ball is being dropped.
