  3. 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 oRead more

    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.

  4. 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
