A particle moves in a circle uniformly such that it completes a circle in 2 sec. During half a turn its centripetal
\( \mathrm{P} \) acceleration change by \( 6 \mathrm{~m} / \mathrm{s}^{2} \). Choose the correct option(s).

W
(1) the radius of the circle is \( \left(3 / \pi^{2}\right) \mathrm{m} \).
(2) the magnitude of change in velocity during \( 1 \mathrm{~s} \) is \( 3 / \pi \mathrm{m} / \mathrm{s} \)
(3) the tangential velocity of the particle is \( 3 / \pi \mathrm{m} / \mathrm{s} \).
(4) the particle is moving in anticlockwise sense as seen from above.
