Answer» Sixteen beads in a string are placed on a smooth inclined plane to inclination $θ = s i n^{- 1} (\frac{1}{3})$ , such that some of them lie along the incline, whereas the rest hang over the top of the plane. If $N$ beads lie along inclined plane then the acceleration of the bead (of the vertical portion) just below vertex is $\frac{g}{2}$ downwards. Value of $N$ is
