neutron has no charge. In nucleus, why force of attraction exists between proton and neutron in nucleus.

Question

anonymous · Answer

wait what?!.. protons repel neutrons?

anonymous · Answer

coz of strong nuclear force... it is an exchange force nd greater than electromagnetic force

anonymous · Answer

what is the cause for nuclear force?
 like the cause for Coulomb force is Electric field.

The cause for nuclear force is not all that easy to understand

as far as i know.. its called as an exchange force.. 

imagine two kids who like a  toy very much.. and if they have only one toy.. then they woudl stick to each other.. right?

similarly here protons and neutrons are exchanging a class of elementary particles called as pi mesons (pions).. there are three types.. so its this exchange that keeps them together!

but i think this is just a very crude and a highly simplified explanation.. definitely to dig deep you need to go for quantum mechanics!

Wait there are two types of nuclear forces (the strong nuclear force and the weak nuclear force) which are we dealing with?

anonymous · Answer

one of the probable answer is the Exchange of Mesons
