A particle is projected from point A with speed u and angle of projection is o 60° . At some instant magnitude of velocity of particle is v and it makes an angle θ with horizontal. If radius of curvature of path of particle at the given instant is 8/3 √3 times of the minimum radius of curvature during the whole flight, then angle θ is
(A) θ = 37
(B) θ = 30
(C) θ = 45
(D) θ =15
