MHT CET Physics question
A rod of length 'L' is hung from its one end and a mass 'm' is attached to its free end. What tangential velocity must be imparted to 'm', so that it reaches the top of the vertical circle? (g = acceleration due to gravity) [MHT-CET 2022, MHT-CET 2022]
Answer: (B)
Solution
For a rigid rod the mass only needs to just reach the top with zero speed: , so (the value
