Q.

Statement 1: If the extremities of the latus rectum of the

 ellipse   x2a2+y2b2=1 (a> b), having positive ordinates 

lies on the parabola x2=2(y2),  then,  a=2

Statement 2: If the length of the latus rectum of the  

ellipse  x2a2+y2b2=1  is equal to the distance between 

the foci, then the eccentricity e of the ellipse satisfies 

e2+e1=0

Detailed Solution

 Statement-2 is true by definition of conjugate

 diameters.  

Let y=mx and y=mx x be two conjugate diameters of

the ellipse x2a2+y2b2=1.  Let  (h,k) be the mid point 

of chord whose step is m then  

hxa2+kyb21=h2a2+k2b21

m=b2a2hk Locus of  (h, k)  is y=b2a2mx

b2a2m=mmm=b2a2  . (using statement-2)

and thus statement- I is false.
