A main revolves a stone of mass `m` tied to the end of a string in a circle of radius R The net force at the lowest and beight point of the circle directed vertical downward are
Here`T_(1),T_(2)` and `(v_(1),v_(2))` denote the tension in the string (and the speed of the stone) at the lowest and highest points, respectively.

A stone of mass m tied 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 the corresponding values at the highest points.

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.

A stone of mass m tied 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.

A stone of mass m tied 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] Lowest point Highest point T_(1) and V_(1) denote the tension and speed at the lowest point T_(2) and V_(2) denote the corresponding values at the highest points.

A stone of mass m tied 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] Lowest point Highest point T_(1) and V_(1) denote the tension and speed at the lowest point T_(2) and V_(2) denote the corresponding values at the highest points.

A small body tied to one end of the string is whirled in a vertical circle. Find the velocity and tension at the lowest and highest point of the circle respectively.

A child revolves a stone of mass 0.5 kg tied to the end of a string of length 40 cm in a vertical circle. The speed of the stone at the lowest point of the circle is 2 m/s calculate the tension in the string at this point.
