When a body is whirled in a vertical circle such that its total mechanical energy is constant with critical velocities then tension in the string changes with time. Arrange the following in increasing order of tension when (i) String is horizontal (ii) String makes an angle 0^(0)with downward vertical (iii) String makes an angle of 180^(0) with downward vertical (iv) String makes an angle 120^(0) with down Ward vertical

1.	When a body is whirled in a vertical circle such that its total mechanical energy is constant with critical velocities then tension in the string changes with time. Arrange the following in increasing order of tension when (i) String is horizontal (ii) String makes an angle 0^(0)with downward vertical (iii) String makes an angle of 180^(0) with downward vertical (iv) String makes an angle 120^(0) with down Ward vertical
