A) \[2{{x}^{2}}+{{y}^{2}}={{a}^{2}}\]
B) \[{{x}^{2}}+{{y}^{2}}={{a}^{2}}\]
C) \[{{x}^{2}}-{{y}^{2}}={{a}^{2}}\]
D) \[2{{x}^{2}}-{{y}^{2}}={{a}^{2}}\]
Correct Answer: B
Solution :
[b] \[\because \]The fixed point A & B will be the extreme point on the diameter of a circle. P be any point on the circle. So, equation of the circle, whose radius is a and centre be the origin be \[{{x}^{2}}+{{y}^{2}}={{a}^{2}}\] Hence, option [b] is correct.You need to login to perform this action.
