A particle is kept fixed on a turntable rotating uniformly. As seen from the ground the particle goes in a circle, its speed is 20cm/s & acceleration is 20cm/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 & acceleration will be:
