A small body of mass \( m \) hangs at one end of a string of length a, the other end of which is fixed. It is given a horizontal velocity \( u \) at its lowest position so that the string would just becomes slack, when it makes an angle of \( 60^{\circ} \) with the upward drawn vertical line. Find the tension in the string at point of projection.
