\textbf{Given:}

\text{The points A(0,0), B(-a,0) and $\angle{APB}=\frac{\pi}{2}$}

\textbf{To find:}

\text{The locus of P}

\text{Let the coordinates of P be (h,k)}

\text{Since $\angle{APB}=\frac{\pi}{2}$,}

\textbf{Slope of AP}{\times}\textbf{Slope of PB}=-1

\dfrac{k-0}{h-0}{\times}\dfrac{k-0}{h+a}=-1

\dfrac{k}{h}{\times}\dfrac{k}{h+a}=-1

\dfrac{k^2}{h^2+ah}=-1

k^2=-h^2-ah

\implies\,h^2+k^2+ah=0

\therefore\textbf{The locus of P is $\bf\,x^2+y^2+ax=0$}

Find more:

B and c are fixed points having coordinates (3,0) and (-3,0) respectively. If the vertical angle bac is 90 then locus
