A particle moves along a closed trajectory in a central field of force where the particle's potential energy `U=kr^2` (k is a positive constant, r is the distance of the particle from the centre O of the field). Find the mass of the particle if its minimum distance from the point O equals `r_1` and its velocity at the point farthest from O equals `v_2`.
