The equation of a hyperbola, whose foci are $(5, 0)$ and $(-5, 0)$ and the length of whose conjugate axis is $8$, is
Let the eccentricity of the hyperbola $\frac{x^2}{a^2}-\frac{y^2}{b^2}=1$ be reciprocal to that of the ellips $x^2+4 y^2=4$. If the hyperbola passes through a focus of the ellipse, then
$(A)$ the equation of the hyperbola is $\frac{x^2}{3}-\frac{y^2}{2}=1$
$(B)$ a focus of the hyperbola is $(2,0)$
$(C)$ the eccentricity of the hyperbola is $\sqrt{\frac{5}{3}}$
$(D)$ the equation of the hyperbola is $x^2-3 y^2=3$
An ellipse intersects the hyperbola $2 x^2-2 y^2=1$ orthogonally. The eccentricity of the ellipse is reciprocal of that of the hyperbola. If the axes of the ellipse are along the coordinate axes, then
$(A)$ Equation of ellipse is $x^2+2 y^2=2$
$(B)$ The foci of ellipse are $( \pm 1,0)$
$(C)$ Equation of ellipse is $x^2+2 y^2=4$
$(D)$ The foci of ellipse are $( \pm \sqrt{2}, 0)$
