A turn table which is rotating uniformly...

A turn table which is rotating uniformly has a particle placed on it. As seen from the ground, the particle goes in a circle with speed 20 `cm//s` and acceleration 20 `cm//s^2`. The particle is now shifted to a new position where radius is half of the original value . the new values of speed and acceleration will be

A

`10cm//s,10cm//s^2`

B

`10cm//s,80cm//s^2`

C

`40cm//s,10cm//s^2`

D
