29. Three point masses 5m, 2m, and m are connected by a thin, negligible mass rod with length L. The 5m and m masses are at the ends and 2m mass is half way between the ends. If we pivot this object at a point half way between the 2m and m masses, as shown, what will be its angular frequency? The acceleration due to gravity is ay = -9. pivot 2m A. 3gL 8 B. 3L 9 c. 3g D. 10 5m gL m L
