A) 4 units
B) 6 units
C) 8 units
D) 10 units
Correct Answer: A
Solution :
[a] Given equation of ellipse is \[\frac{{{x}^{2}}}{4}+\frac{{{y}^{2}}}{9}=1\] \[\Rightarrow \frac{{{x}^{2}}}{{{(2)}^{2}}}+\frac{{{y}^{2}}}{{{(3)}^{2}}}=1\Rightarrow a=2\] and \[b=3\] Length of major axis \[=2a=4\] Since, we have Sum of the focal distance of a point on ellipse = length of major axis. \[\therefore \] Required Ans = 4 units.You need to login to perform this action.
