Question

The sum of focal distance of any point on the ellipse with major and minor axes as $2 a$ and $2 b$, respectively is equal to

(a) $2 a$

(b) $2 \frac{a}{b}$

(c) $2 \frac{b}{a}$

(d) $\frac{b^2}{a}$

Answer 1

SOLUTION — We know the sum of focal distance of any point on the ellipse always equal to the length of major axis i.e., is it equal to $2 a$

So, The correct option of this question will be (A).
