a weightles thread can bear upto 3.7kgwt a stone of mass 500 gm is tied to it and revolved in a circular path of radius 4m in a vertical plane. if g=10m/s^2, then the maximum angular velocity of stone can be???

Question

anonymous · Answer

no the ans is 16m/sec

anonymous · Answer

Tension is maximum at the bottom point where T= mg+mrw^2
$$w = \sqrt{T - mg/mr}$$


w = sqrt (37 -5 / 2)=  4 rad/s

tangential velocity v =rw =16m/s
