Inside the nucleus there would always be the repulsive forces. The binding energy puts the nucleus binded but the energy eventually gets exhausted, but the repulsive forces are ever lasting.
To bind the nucleus there should be energy always, I mean to bind the nucleus continuously there should be energy supplied continuously.
This binding energy is obtained by mass defect, so to continuously provide energy to bind the nucleus, mass should be continuously be dissappearing but this doesn't happen.
So from where is the energy to bind the nucleus coming continuously? ?
