A particle is kept fixed on as turntable rotating uniformly. As seen from the ground the particle goes in a circle,its speed is 20 cm/s and acceleration is 20 cm/s^2 The particle is now shifted to a new positon to make the radius half of the original value. The new values of the speed and acceleration will be

A

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

B

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

C

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

D

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