The angular velocity of a particle moving in a circle of radius \( 50 \mathrm{~cm} \) is increased in \( 5 \mathrm{~min} \) from 100 revolutions per
\( \mathrm{P} \) minute to 400 revolutions per minute. Find the tangential

W. acceleration of the particle.
(2) \( \pi / 30 \mathrm{~m} \mathrm{~s}^{-2} \)
(1) \( 60 \mathrm{~m} \mathrm{~s}^{-2} \)
(4) \( \pi / 60 \mathrm{~ms}^{-2} \)
