Two particles 
and 
, move with constant velocities 
and 
. At the initial moment, their position vectors are 
and 
, respectively. The condition for particles 
and 
for their collision is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Let the particles 
and 
collide at time 
. For their collision, the position vectors of both
particles should be same at time 
.
… ..(i)
Also, 
or 
Substituting the value of 
in Eq. (i), we get
