two particles A and B are placed in gravity free spaceat (0,0,0)m and (30,0,0)m respectively. Particle A is projected with a velocity (5i+10j+5k)ms-1while particle B is projected with a velocity (10i+5j+5k)ms-1\nsimultaneously. then(A)they will collide at (10,20,10)m\n(B)they will collide at(10,10,10)m\n(C)they will never collide\n(D)none of the above
