A particle is suspended vertically from a point O by an inextensible massless string of length L. A vertical line AB is at a distance `L//8` from O as shown in figure. A horizontal velocity `u` is imparted to tha particle. At horizontal velocity `u` is imparted to the particle. At some point, its motion ceases to be circular and eventually the object passes through line AB. At the instant of crossing AN, its velocity is horizontal. Find out the value of u.
