Question
Two particles 1 and 2 are projected with same speed 
as shown in figure. Particle 2 is on the ground and particle 1 is at a height 
from the ground and at a horizontal distance 
from particle 2. If a graph is plotted between and for the condition of collision of the two then ( on 
-axis and on 
-axis)
- It will be a parabola passing through the origin
- It will be straight line passing through the origin and having a slope of
- It will be a straight line passing through the origin and having a slope of
- It will be a straight line not passing through the origin
The correct answer is: It will be straight line passing through the origin and having a slope of
Assuming particle 2 to be at rest, substituting in
We have 
or 
Which is a straight line passing through origin with slope
