MHT CET 2025 Physics question
A weightless thread can bear tension up to 3.7 kg wt. A stone of mass 500 gram is tied to it and revolved in circular path of radius 4 m in vertical plane. Maximum angular velocity of the stone will be (acceleration due to gravity, m/s)
Answer: (B)
Solution
The tension is greatest at the lowest point, where . Maximum tension kg wt N; kg so N. Then $37-5=0.5×ω^2×4⇒
