A cabin is moving upwards with a constant acceleration g. A boy standing in the cabin wants to whirl a particle of mass m in a vertical circle of radius l. ( Mass is attached to an ideal string.) Calculate minimum

A simple pendulum of length l and mass m free to oscillate in vertical plane. A nail is located at a distance d = l - a vertically below the point is released from the position where the string
