If the minor axis of an ellipse subtends an angle `60^(@)` at each focus then the eccentricity of the ellipse is

If the minor axis of an ellipse subtends an angle 90^(@) at each focus then the eccentricity of the ellipse is

If the minor axis of an ellipse subtends an angle 60^(circ) at each focus then the eccentricity of the ellipse is

If the minor axis of an ellipse subtends an angle 60^(@) at each focus then e =

If the minor axis of an ellipse subtends an angle of 60^(@) at each focus of the ellipse, then its eccentricity, is

If the minor axis of an ellipse subtends an angle of 60^(@) at each focus of the ellipse, then its eccentricity, is

If the length of the major axis of an ellipse is 17/8 times the length of the minor axis, then the eccentricity of the ellipse is

In an ellipse, if the lines joining focus to the extremities of the minor axis form an equilateral triangle with the minor axis, then the eccentricity of the ellipse is :

In an ellipse, if the lines joining focus to the extremities of the minor axis form an equilateral triangle with the minor axis, then the eccentricity of the ellipse is

In an ellipse,if the lines joining focus to the extremities of the minor axis form an equilateral triangle with the minor axis,then the eccentricity of the ellipse is

If the angle between the lines joining the end points of minor axis of an elipes with its one focus is pi/2, then the eccentricity of the ellipse is-
