Point 2
@Gyro Gearloose
Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.also to PE thing
i think its like
in bigger nuclei
even if there's another proton or neutron all the way over on one side of the nucleus
some other proton/neutron sitting on the other side won't feel a lot of attraction
cause of the relatively larger distance
and so the net force is approximately the force exerted by its nearby nucleons only
and since the nuclear density is constant-ish
the binding energy per nucleon happens to be constant-ish
idk this makes the most sense to me rn
Kinda makes sense because the BEPN Curve shows constancy for 30<A<170
Also can u explain the potential energy thing written below point 3? @professional_procrastinator
these lines?
a negative potential energy usually implies an attractive force is acting on a particle
matlab it's in a "bound" state
people are often interested in the minima of the potential energy
because it corresponds to the most stable state in the nucleus
so at distances equal to or greater than 0.8fm, the nuclear force is attractive and keeps the nucleons bound in the nucleus
but if they ever get too close
like say 0.5 fermi
then it gets repulsive
hence the positive potential energy
Thats means nuclear force can be attractive as well as repulsive
yes
Depends on the distance
yes
Aight thanks a lot
Would u mind taking a look at the other nuclear doubt that i asked
sure
