A body moves along a horizontal circular path of radius 5 m. The coefficient of friction between the surface of the path and the body is 0.5 . The maximum angular velocity (in rad/sec) with which the body should move so that it does not leave the path is (Take g = 10 m/s2 ):

Given :
r = 5m
μ = 0. 5 μmg
The body does not leave the path when ,
μmg = mw2r
ω = √ μg/ r
ω = √ 0.5×10/ 5= 1 rad / sec
