Question
A thin rod free to rotate about a horizontal axis through one end O is initially in unstable equilibrium in position 1 and falls due to gravity on being displaced slightly. In positions 2, 3 and 4 it makes 60o, 90o and 180o with the upward vertical. Let ω2, ω3 and ω4 be angular velocities of the rod in theses positions then :
Options
A.ω4 = 2ω3
B.ω4 = 2ω2
C.ω3 = 1.5ω2
D.ω3 = ω2√2
