Two particles 1 and 2 move with constant velocities V1 and V2. At initial moment their radius vectors are equal to r1 and r2. How must these 4 vectors be interrelated for the particles to collide?...

velocity of b with respect to A is : V2 – V1  (with vectoral sign on top of each term) ----> 1
position of b with respet to A is: r2 – r1
Particle B will collide with A, if velocit of B wrt A is directed to A,
Then 
V2 – V1(with vectororal sign on top of each) = r2 – r1 (vector)
------------                                                             -----------
V2 – V1 (with modulus sign )                             r2 – r1 (modulus)
HOPE THIS HELPS!
THANK YOU
