Answer:
Velocity of the particle in circular motion is equal to w.r, so if w is constant the velocity is proportional to r. Here the particle is kept at the half radius. ∴ Velocity will be half i.e., 10sm.
Similarly, acceleration is w2r, here too w2 is constant. So acceleration is also proportional to ‘r’.
Making radius half will make acceleration half i.e. 10cm/s2
