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 the fig.
The object is given a horizontal velocity u. At some point, its motion ceases to be circular and eventually the object passes through the line AB. At the instant of crossing AB, its velocity is horizontal. Find u
