Question : 89 of 160

Marks: +1, -0

A uniform rod of mass 'm' and length 'l' is pivoted smoothly at ‘O' as shown in figure. If a horizontal force ‘F' acts at the bottom of the rod and 'ω' is the angular velocity of the rod which is a function of angle of rotation ‘0\ then the maximum angular displacement of the rod is
(Acceleration due to gravity = g)

θ = 2sin−1(
2F
mg
)
θ = 2cos−1(

mg
)
θ = 2tan−1(
2F
mg
)
θ = 2cot−1(
