A bead of mass \( 5 \mathrm{~kg} \) is free to slide on the horizontal \( \operatorname{rod} A B \). They are connected to two identical springs of natural length \( h \mathrm{~ms} \). as shown. If initially bead was at \( O \& M \) is vertically below \( L \) then, velocity of bead at point \( N \) will be :
(A) \( 5 \mathrm{hm} / \mathrm{s} \)
(B) \( 40 \mathrm{~h} / 3 \mathrm{~m} / \mathrm{s} \)
Figure 3.104
(C) \( 8 h \mathrm{~m} / \mathrm{s} \)
(D) None of these
