A) Hyperbola
B) Ellipse
C) Parabola
D) Circle
Correct Answer: D
Solution :
[d] \[(\hat{i}-2x\hat{j}-3y\hat{k}).(\hat{i}+3x\hat{j}+2y\hat{k})=0\] \[1-6{{x}^{2}}-6{{y}^{2}}=0\] \[-6{{x}^{2}}-6{{y}^{2}}=-1\] \[{{x}^{2}}+{{y}^{2}}=\frac{1}{6}\] \[{{x}^{2}}+{{y}^{2}}={{\left( \sqrt{\frac{1}{6}} \right)}^{2}}\]You need to login to perform this action.
