09 A massive bead is threaded on a light rod that is pivoted to a fixed point O at one end Initially the rod is held in a horizontal position and the bead is at a distance from the pivoted end When the rod is released it rotates in a vertical plane and the bead slides down the rod due to gravity Which of the following statements best suits for dependence of the angle 9 that the rod makes with the horizontal on time t A If coefficient of friction between the rod and the bead is negligible 0 tan B If coefficient of friction between the rod and the bead is finite 0 tangt 2 C If coefficient of friction between the rod and the bead is finite 0 tan D None of the above statements is true 2 gt 21
