In the figure shown, the system is released from rest. Find the velocity of block A when block B has fallen a distance ' \( \ell \) '. Assume all pullevs to be massless and frictionless.
(A) \( \sqrt{\frac{g \ell}{5}} \)
(B) \( \sqrt{g \ell} \)
(C) \( \sqrt{5 g \ell} \)
(D) None of these
\( \mathrm{P} \)
\( \mathrm{W} \)
