A uniform rod pivoted at upper end is released when it is making an angle of 60 o . Find the radial force acting on a particle of mass dm at its tip when it makes an angle of 37 0 with the vertical.
Text Solution
Verified by ExpertsThe correct answer is:
C
I ω ω 2 = mg 
(cos 37 – cos 60)
or 
ω ω 2 = mg l (.8 - 5)
F rad = dm 
= 0.9 (dm)g
