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