A STONE OF MASS 1KG TIED TO A LIGHT INEXTENSIBLE STRING OF LENGTH = 10/3m , WHIRLING IN A CIRCULAR PATH IN A VERTICAL PLANE. THE RATIO OF MAX. TENSION IN THE STRING TO THE MIN. TENSION IN THE STRING IS 4. THE SPEED OF THE STONE AT THE HIGHEST POINT OF THE CIRCLE IS :
1. 10 m/s
2. 5(2)^1/2 m/s
3. 10(3)^1/3 m/s
4. 20 m/s

The tension of a string is different due to centrifugal force. While
gravity is always directed downward, the centrifugal force is directed
upward at the highest point and downward at the lowest point. So, the
tension force is a sum of gravity and centrifugal force at the lower
point, and a difference at the highest, see the first two Eqns. All
the rest is mathematics.
