C A massive bead is threaded on a long light rod one end of which is pivoted to a fixed point O Initially the rod is held horizontally and the bead is at a distance I from the pivot Coefficient of friction between the rod and the bead is u Which of the following statements correctly describe relation between angle that the rod makes with the horizontal after the rod is released and time t 1 a If u is negligible tan b If u is finite tan 1 gt 21 gt 21 c If u is finite is smaller than tan 1 gt 21 d None of the above statements is correct by a finite amount
