Explanation to the Answer
→ Velocity of the particle in a circular motion is equal to ωr , so if ω is constant the velocity is proportional to the radius. Here the particle is kept at half radius therefore velocity will be half ie = 10 cm/s.
Similarly acceleration is ω²r , here too, ω² is constant, so acceleration is also proportional to 'r'. In this case too, making radius half will make acceleration half ie = 10 cm/s².
Answer: 10 cm/s, 10 cm/s^2
