Two particles A and B, move with constant velocities V₁ and V₂. At the initial moment their position vectors are r₁ and r₂ respectively. The condition for particles A and B for their collision is
Options
(a) r₁.v₁=r₂.v₂
(b) r₁xv₁=r₂xv₂
(c) r₁-r₂=v₁-v₂
(d) r₁-r₂/|r₁-r₂|=v₁-v₂/|v₁-v₂|
Correct Answer:
r₁-r₂/|r₁-r₂|=v₁-v₂/|v₁-v₂|
