Q. The difference in focal distance of any point on the hyperbola $\frac{x^{2}}{16} - \frac{y^{2}}{9} = 1$ is
A) 8
B) 9
C) 0
D) 6
Explanation
(a)
In the given equation of hyperbola
$a = 4\$ and $b = 3$
We know that the difference of focal distance of any point of the hyperbola$= 2a$
$= 2 \times 4 = 8$
