Two particles are moving along two long ...

Two particles are moving along two long straight lines, in the same plane with same speed equal to `20 cm//s.` The angle between the two linse is `60^@` and their intersection point isO. At a certain moment, the two particles are located at distances 3m and 4m from O and are moving twowards O. Subsequently, the shortest distance between them will be
