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