Question
A particle originally at a rest at the highest point of a smooth circle in a vertical plane, is gently pushed and starts sliding along the circle. It will leave the circle at a vertical distance 
below the highest point such that
The correct answer is:
From law of conservation of energy, potential energy of fall gets converted to kinetic energy.
Also, the horizontal component of force is equal centrifugal force.
From Eq. (i)
