Question

$Assertion\left(A\right):$ The eccentricity of an ellipse is $\frac{3}{5}.$
$Reason\left(R\right):$ The equation of the ellipse is $x=5\cos \theta ,y=4\sin \theta .$

• A. Assertion and reason both are correct and reason is an explanation.
• B. Assertion and reason both are correct and reason is not an explanation.
• C. Assertion is incorrect and reason is correct.
• D. Assertion is correct and reason is incorrect.

Answer 1

The correct option is B Assertion and reason both are correct and reason is not an explanation.

$x=5cos\theta ,y=4sin\theta$
$a=5,b=4$
$e^2=\frac{25-16}{25}$
$e=0.6$
