Two thin rods AB & CD of lengths 2a & 2b move along OX & OY respectively, when ‘O’ is the origin. The equation of the locus of the centre of the circle passing through the extremities of the two rods is :
- x2 + y2 = a2 + b2
- x2 – y2 = a2 – b2
- x2 + y2 = a2 – b2
- x2 – y2 = a2 + b2
Answer
(B) x 2 – y 2 = a 2 – b 2
