Two particles A and B are projected simultaneously from a point situated on a horizontal plane. The particle A is projected vertically up with a velocity uA while the particle B is projected up at an angle of 30o with horizontal with a velocity uB. After 5 sec the particles were observed moving mutually perpendicular to each other. The velocity of projection of the particle uA and uB respectively are
- 50 ms–1, 100 m/s
- 100 ms–1, 50 ms–1
- uA > 25 m/s and uB <50 m/s
- none of these
Answer
(A) 50 ms–1, 100 m/s
