A particle of mass m is tied to a light string of length l and rotated along a vertical circular path. What should be the minimum speed at the highest point of its path so that the string does not become slack at any position ?

A particle of mass m is fixed to me one end of a light right rod of length l and rotated in a vertical circular path about its other end. The minmum speed of the particle at its highest point must be

A stone is tied to a weightless string and revolved in a vertical circle of radius 5 m . What should be the minimum speed of the stone at the highest point of the circle so that the string does not slack ? What should be the speed of the stone at the lowest point of vertical circle ? Take g = 9.8 ms^(2) .

A stone of mass m is tied to a string of length l and rotated in a circle with a constant speed v . If the string is released, the stone flies
