A body of mass m is projected horizontally with a velocity v from the top of a tower of
height h, and it reaches the ground at a distance x from the foot of the tower. If a second body of mass 2m is projected horizontally from the top of a tower of height 2h, it reaches the ground at a distance 2x from the foot of the tower. The horizontal velocity of the second body is
A
v
B
2v
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
For the first body, 
… (i)
and 
… (ii)
… (iii)
For second body, let 
be the velocity of projection,
… (iv)
On dividing eq. (iii) by eq. (iv), we get
