Column I, Column II An ellipse passing through the origin has its foci (3, 4) and (6,8). Then the length of its minor axis is, p. 8 If `P Q` is a focal chord of the ellipse `(x^2)/(25)+(y^2)/(16)=1` which passes through `S-=(3,0)` and `P S=2,` then the length of chord `P Q` is, q. `10sqrt(2)` If the line `y=x+K` touches the ellipse `9x^2+16 y^2=144 ,` then the difference of values of `K` is, r. 10 The sum of distances of a point on the ellipse `(x^2)/9+(y^2)/(16)=1` from the foci is, s. 12
