A body is moving in a vertical circle of radius r by a string. If the ratio of maximum to minimum speed is sqrt(3):1 , the ratio of maximum to minimum tensions in the string is

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 bob of mass 100 g tied at the end of a string of length 50 cm is revolved in a vertical circle with a constant speed of 1 ms^(-1) . When the tension in the string is 0.7 N, the angle made by the string with the vertical is (g = 10 ms^(-2))
