A particle of mass \( 1 \mathrm{~kg} \) moves in a circular path of radius \( 1 \mathrm{~m} \) such that its speed varies with time
\( \mathrm{P} \) as per equation \( v=3 t^{2} \mathrm{~m} / \mathrm{s} \) where time \( t \) is in

W. seconds. The power delivered by the force acting on the particle at \( \mathrm{t}=1 \mathrm{~s} \), is :-
(1) \( 36 \mathrm{~W} \)
(2) \( 20 \mathrm{~W} \)
(3) \( 18 \mathrm{~W} \)
