Two particles A and B projected simultaneously from a point situated on a horizontal place. The particle A is projected vertically up with a velcity vA while the particle B is projected up at an angle 30∘ with horizontal with velocity vB. After 5s the particles were observed moving mutually perpendicular to each other. The velocity of projection of the particle vA and vB respectively are:
