The gravitational potential of two homogeneous spherical shells A and B (separated by large distance) of same surface mass density at their respective centers are in the ratio 3 : 4. If the two shells coalesce into single one such that surface mass density remains same, then the ratio of potential at an internal point of the new shell to shell A is equal to
