a bob of mass m is suspended by a light string of length l. it is imparteed a horizontal velocity(v)at the lowest position such that it just completes the vertical cycle. obtain an expression for- 1.)minimum velocity of the bob at the lowest position so as to complete the vertical circle. 2.)velocities when string swings an angle of 90 degree and 180 degree w.r.t initial position. 3.)ratio of tension in string at lowest position and at angle 90 degree w.r.t the lowest position.
