A particle of mass \( m \) moves in a circular path of radius \( r \), under the action of force which delivers it constant power \( p \) and increases its speed. The
\( \mathrm{P} \) angular acceleration of particle at time \( (t) \) is

W proportional
(1) \( \frac{1}{\sqrt{t}} \)
(2) \( \sqrt{t} \)
(3) \( t^{0} \)
(4) \( t^{3 / 2} \)
