Question
A particle is attached to an end of a rigid rod. The other end of the rod is hinged and the rod rotates always remaining horizontal. It’s angular speed is increasing at constant rate. The mass of the particle is m. The force exerted by the rod on the particle is $\overset{\rightarrow}{F}$, then
Options
A.F ≥ mg
B.F is constant
C.The angle between $\overset{\rightarrow}{F}$ and horizontal plane decreases.
D.The angle between $\overset{\rightarrow}{F}$ and the rod decreases.
Solution
Sol. F is Resistant of mg & Tension force
So F ≥ mg
