A stone tied to a rope is rotated in a vertical circle with uniform speed. If the difference between the maximum and minimum tensions in the rope is 20 N, mass of the stone in kg is (take, g= 10 ms^(-2))

1.	A stone tied to a rope is rotated in a vertical circle with uniform speed. If the difference between the maximum and minimum tensions in the rope is 20 N, mass of the stone in kg is (take, g= 10 ms^(-2))
Answer» `0.75` `1.0` `1.5` `0.5` Solution :We know that the difference between the maximum and minimum TENSIONS in the rope `T_(max)-T_(min)=2MG` Here, `T_(max)-T_(min)=20` Now, mass of the STORE F = ma `m=(F)/(a)=(20)/(2xx10)=1kg`
