Two particles, 1 and 2 move with constant velocities v 1 and v 2 along two mutually perpendicular straight lines towards the intersection point O. At the moment t=0 the particles were located at the distance l 1 and l 2 from the point O. How soon will the distance between the particles become the smallest? What is it equal to?
