• # question_answer Probability of product of a perfect square when two dice are thrown together A)  $\frac{1}{9}$                                    B)  $\frac{2}{13}$ C)  $\frac{2}{9}$                                    D)  $\frac{4}{9}$

Total outcomes = 36 Favorable outcomes $v=\sqrt{2gh}=\sqrt{2\times 980\times 460}\,\,cm/s$ $=\sqrt{920\times 980}\,cm/s$ $=Q=q+q'$ $\therefore$    $q'=(Q-q)$
