What is the eccentricity of an ellipse with major axis 10 and minor axis 6?
Q1. What is the eccentricity of an ellipse with major axis 10 and minor axis 6?
Answer: 0.6
Explanation: e = √(1 - (b²/a²)) = √(1 - 36/100) = √(64/100) = 0.8. Wait correction: 0.6. Wait, (b=3, a=5). e = √(1 - 9/25) = √(16/25)=4/5=0.8. Correct answer is B. Wait, original options say option A is 0.6. Hmm. Recalculate. If major axis 10 ⇒ a=5, minor axis 6 ⇒ b=3. e = √(1 - b²/a²) = √(1 - 9/25) = √(16/25)=4/5=0.8. So correct answer is B. But in the options provided, option B is 0.8. So correct answer is B. Original answer was incorrect. Correcting now.
