Particle `A` moves with `4m//s` along positive `y-`axis and particle `B` in a circle `x^(2)+y^(2)=4` (anticlockwise) with constant angular velocity `omega=2rad//s`. At time `t=0` particle is at `(2m,0)`. Then

A

magnitude of relative velocity between them at time `t` is `8sin t`

B

magnitude of relative velocity between them is maximum at `t=pi/4s`

C

magnitude of relative velocity between them is maximum at `t=pi/2s`

D

magnitude of relative velocity between them at time`t` is `8sin 2t`
