A stone is fastened to one end of a string and is whirled in a verticla circle of radius R. Find the minimum speed the stone can have at the highest point of the circle.

A stone is fastened to one end of a string and is whirled in a verticla circle of radius R. Find the minimum speed the stone can have at the highest point of the circle.

A stone is fastened to one end of a string and is whirled in a verticla circle of radius R. Find the minimum speed the stone can have at the highest point of the circle.

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 is tied to one end of a string and rotated in a vertical circle . What is the difference in tensions of the string at lowest and highest points of the vertical circle ?

A stone of mass 0.3g is tied to one end of string 0.8m long and rotated in a vertical circle At what speed of the stone will the tension in the string be zero at the highest point of the circle ? What will be the tesion at the lowest point in this case ? Take g = 980 cm^(-2) .

A stone of mass 0.3 kg is tied to one end of a string 0.8 m long and rotated in a vertical circle. At what speed of the ball will the tension in the string be zero at the highest point of the circle? What would be the tension at the lowest point in this case ? Given g = 9.8 ms^(-2) ?

A stone of mass mtied to the end of a string revolves in a vertical circle of radius R. The net forces at the lowest and highest points of the circle directed vertically downwards are : [Choose the correct alternative] T_1 and v_1 denote the tension and speed at the lowest point. T_2 and v_2 denote corresponding values at the highest point.

IF a stone is tied to one end of the string and whirled in verticle circle, then the tension in the string at the lowest point is equal to
