A particle is moving with constant angular acceleration \( =\alpha \) in a circular path of radius \( \sqrt{3} \mathrm{~m} \). At
\( \mathrm{P} \)
\( \mathrm{t}=0 \), it was at rest and at \( \mathrm{t}=1 \mathrm{sec} \), the magnitude of
W
its acceleration becomes \( \sqrt{6} \mathrm{~m} / \mathrm{s}^{2} \), then \( \alpha \) is:
(1) \( 2 \mathrm{rad} / \mathrm{s}^{2} \)
(2) \( \sqrt{3} \mathrm{rad} / \mathrm{s}^{2} \)
(3) \( \sqrt{2} \mathrm{rad} / \mathrm{s}^{2} \)
(4) \( 1 \mathrm{rad} / \mathrm{s}^{2} \)
