Solution:

Since, we know that
Nuclear forces are responsible for keeping the nucleons (neutron and proton) bound in a nucleus. The range of nuclear forces very short
Nuclear forces are, one an average much stronger than electromagnetic forces times stronger in their range
Nuclear forces are strongest of all the four fundamental forces
