Question : A small particle of mass π is projected at an angle π with the π₯-axis with an initial velocity π£0 in the π₯-π¦ plane as shown in the figure. At a time π‘ < π£0 /sinΞΈ π , the angular momentum of the particle is
(A) -mgv_{0}t^{2}\cos \theta \widehat{j}
(B) mgv_{0}t^{2}\cos \theta \widehat{k}
(C) -\dfrac{1}{2}mgv_{0}t^{2}\cos \theta \widehat{K}
(D) \dfrac{1}{2}mgv_{0}t^{2}\cos \theta \widehat{i}
Answer : option (C)
