86. The dependence of the potential energy of a particle in a central force field on the distance r from the center of the field is given by P (r) = A / r2 - B / r, where A and B - are positive constants. Determine the value of r0, corresponding to the equilibrium position of the particle. Is this the position of stable equilibrium position?
