Q4 of 76 Page 26

The eccentricity of the ellipse if its latus - rectum is equal to one half of its minor axis, is

Given that we need to find the eccentricity of the ellipse whose latus - rectum is one half of the minor axis.


We know that length of latus rectum is and length of minor axis is 2b.


⇒


⇒ a = 2b.


We know that eccentricity of the ellipse is


⇒


⇒


⇒


∴ The correct option is A
