coordinate

Question: The coordinates of the points A and B are (a, 0) and $(-a,\,0)$ respectively. If a point P moves so that $P{{A}^{2}}-P{{B}^{2}}=2{{k}^{2}}$, when k is constant, then the equation to the locus of the point P , is

1) $2ax-{{k}^{2}}=0$

2) $2ax+{{k}^{2}}=0$

3) $2ay-{{k}^{2}}=0$

4) $2ay+{{k}^{2}}=0$
