Sixteen beads in a string are placed on ...

Sixteen beads in a string are placed on a smooth inclined plane to inclination `theta = sin^(-1) (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 just below vertiex is `g//2`. Value of N is
