    If vertices and foci of an ellipse are \[(0,\pm 13)\] and \[(0,\pm 5)\] respectively, then the equation of an ellipse is

    A) \[-\text{1}\le x\le \text{1}\]      

    B) \[f(x)=x\]

    C) \[f(x)={{x}^{2}}\]            

    D)  None of these

    Correct Answer: A

    Solution :

    Given, vertices\[=(0,\pm \text{ }13)\] and foci\[=(0,\pm \text{ }5)\] Here, we see that x-coodinate is 0, it means major axis lies along Y-axis. Let      \[C{{O}_{2}}\] Here.       \[{{H}_{2}}O\] \[C{{H}_{2}}\]    \[{{\text{C}}_{\text{3}}}{{\text{H}}_{\text{4}}}\] \[{{\text{C}}_{\text{3}}}{{\text{H}}_{\text{3}}}\]              \[{{\text{C}}_{6}}{{\text{H}}_{8}}\] \[5.0k\,mola{{l}^{-1}}\] \[Zn(s)+C{{u}^{2+}}(aq)\xrightarrow{{}}Z{{n}^{2+}}(aq)+Cu(s)\] \[[E_{cell}^{o}=1.1\text{V}]\]Equation of ellipse is\[\text{2}\times \text{1}{{0}^{\text{32}}}\].
