A particle starting from rest, moves in a circle of radius ' r '. It attains a velocity of V_0 {\m} \/ {\s} in the {\n}^{\text{th }} round. Its angular acceleration will be :- [NEET OD 2019]

Correct Answer is : V024πnr2rad∕s2

{ {\V}_0}/{ {\n}} {\rad} \/ {\s}^2

\frac{ {\V}_0^2}{2 \pi n r^2} {\rad} \/ {\s}^2

\frac{V_0^2}{4 \pi n r^2} {\rad} \/ {\s}^2

\frac{ {\V}_0^2}{4 \pi n r} {\rad} \/ {\s}^2
