A particle of mass `m` is subjected to an attractive central force of magnitude `k//r^(2)`, `k` being a constant. If at the instant when the particle is at an extreme position in its closed orbit, at a distance a from the centre of force, its speed is `sqrt(k//2ma)`, if the distance of other extreme position is b. Find `a//b`.
