Two characteristics of nuclear force are:
(i) It is attractive at short ranges (about 1-2 femtometers).
(ii) It is independent of charge and acts equally on protons and neutrons.
The binding energy per nucleon decreases for heavy nuclei like Uranium because the nuclear force becomes less effective over larger distances, while the repulsive electrostatic force between protons increases.
Two characteristic properties of nuclear forces are: (i) Short-range: Nuclear forces act effectively only at distances around 1-2 femtometers. (ii) Independence from charge: They act equally on protons and neutrons, regardless of their electric charge. For more visit here: https://www.tiwariacademy.Read more

. While protons and neutrons are conserved, the total mass of the resulting particles can be slightly less than the initial mass. This “missing” mass is converted into energy. For example, in nuclear fusion, the mass of fused hydrogen atoms is slightly less than the combined mass of the individual atoms, and the difference is released as energy.

The depletion region in a p-n junction is the area near the junction where free electrons and holes recombine, leaving behind fixed ions. This creates an electric field, prevents further charge carrier movement, and acts as an insulating barrier. For more visit here: https://www.tiwariacademy.com/ncRead more
