A body falling from the rest has a velocity v after it falls through a heigh h. The distance it has to fall down further for its velocity to become double, will be

A

2h

B

4h

C

6h

D

8h

Text Solution

Verified by Experts

The correct Answer is:
B

Let at point A initial velocity of body is equal to zero
for path AB: `v^2=0+2gh`
For path AC: `(2v)^2=0+2gx`
`4v^2=2gx`
Solving (i) and (ii) `x=4h`.
