Physics - Circular Motion Question with Solution | TestHub

A stone is thrown from point O on ground with velocity $\overrightarrow{\mathrm{v}}=5\hat{\mathrm{i}}+10\hat{\mathrm{j}}\mathrm{m}/\mathrm{s}$ where x is horizontal and y vertical. Its angular velocity about O when the stone is at maximum height of its trajectory, is(A) $\frac{1}{2}\mathrm{rad}/\mathrm{s}$\\ (B) $\frac{1}{\sqrt{2}}\mathrm{rad}/\mathrm{s}$\\ (C) 1 rad/s\\ (D) $\sqrt{2}\mathrm{rad}/\mathrm{s}$
