A particle is kept fixed on a turntable ...

A particle is kept fixed on a turntable 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 position 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`
