The potential energy of a particle in a force field is: U =A/r^2 − B/r where A and B are positive constants and r is the distance of particle from the centre of field. For stable equilibrium, the distance of the particle is : the distance of the particle is : The potential energy of a particle in a force field is: U =A/r^2 − B/r where A and B are positive constants and r is the distance of particle from the centre of field.
