A particle is moving in circular path with constant tagential acceleration, time \( t \) after the begining of
\( \mathrm{P} \) motion the direction of net acceleration is at \( 45^{\circ} \) to

W. radius vector at the instant. The angular acceleration of the particle at time ' \( t \) ' is proportional to :
(1) \( \frac{1}{\mathrm{t}} \)
(2) \( \frac{1}{t^{2}} \)
(3) \( \frac{3}{t} \)
(4) \( \mathrm{t}^{0} \)
