Sixteen beads in a string are placed on a smooth inclined plane to inclination
θ=sin−1(13), 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
g2 downwards. Value of
N is
