If p_(1),p_(2) are the perpendicular distance from the origin to the two straight lines which are perpendicular to each other, then the locus of the point of intersection of the perpendicular lines is

Answer»

<P>`X^(2)+y^(2)=p_(1)+p_(2)`
`x^(2)+y^(2)=P_(1)^(2)+P_(2)^(2)`
`(x_(1)^(2))/(p_(1)^(2))+(y_(1)^(2))/(p_(2)^(2))=1`
`xy=p_(1)p_(2)`
