A particle is kept fixed on a 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. The particle is now shifted to a new position to make the radius half of the original value. The new value of the speed and acceleration will be:
