Two particles A and B move with constant velocities `v_(1)` and `v_(2)` along two  mutually perpendicular strainght lines. Towards the intersection point O. At moment `t = 0` the particle were located at distance `l_(1)` and `l_(2)` from O respectively. Find the time when they are nearest and also this shortest distance
