Is my answer correct ? I have attached image :- Q- Two particles A and B are placed in gravity free space (0,0,0)m and (30,0,0)m respectively. Particle A is projected with a velocity (5i+10j+5k)m/s while particle B is projected with velocity (10i+5j+5k)m/s simultaneously.Then a)they will collide at (10,20,10)m b) they will collide at (10,10,10)m c) they will never collide. d) they will collide at 2s
