The velocity of a particle varies with t...

The velocity of a particle varies with time as per the law `vec(V) = vec(a) + vec(b)t` where `vec(a) and vec(b)` are two constant vectors. The time at which velocity of the particle is perpendicular to velocity of the particle at t= 0 is

A

`-(|vec(a)|)/(vec(a).vec(b))`

B

`-(|vec(a)|^(2))/(vec(a).vec(b))`

C

`-(vec(a).vec(b))/(|vec(a)|^(2))`

D

None of these
