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 `v_(A)` while the particle B is projected up at an angle `30^(@)` with horizontal with velocity `v_(B)`. After 5s the particles were observed moving mutually perpendicular to each other. The velocity of projection of the particle `v_(A) and v_(B)` respectively are:

A

`50ms^(-1),100ms^(-1)`

B

`100ms^(-1),50ms^(-1)`

C

any value greater than`25ms^(-1),100ms^(-1)`

D

none of the above
