A variable line L is drawn through O(0,0) to meet the line L_(1) " and " L_(2) given by y-x-10 =0 and y-x-20=0 at Points A and B, respectively. Locus of P, if OP^(2) = OA xx OB, is |

Answer» `(y-x)^(2) = 100` `"or " (r "sin" theta - r" cos" theta)^(2) = 200` Hence, the locus is `(y-x)^(2) = 200`. |
