I read Nucleus has Protons & Nutrons. They join together with Nuclear
Force.

What is the Equation of Nuclear Force that joins Protons & Nutrons
together.

Just like Gravitational force is ~ 1/(r^2) where r distance between
two masses.

Gravitational Force=G m1*m2/R^2 where G is gravitatiobnal Constant.

And Electric Foirce is Also ~ 1/(r^2) where r distance between two
charges.

Electrical Force=k` q1*q2/R^2 Where k is dielectric Constant.

Does Nuclear Force which joins protons & nutrons is also proportional
to square of distance between them?

What is the distance betwenn twon Protons in a Nucleus?

What is the technique to know whats going in between Nucleus and to
measure Nuclear force?

The nucleus has protons and neutrons.

It does not work that way. Maybe you should get yourself
a book and read up on it.

Strong and weak forces, yes.

Very complex. See link above.

Just like Gravitational force is ~ 1/(r^2) where r
distance between two masses.

Gravitational Force=G m1*m2/R^2 where G is
gravitatiobnal Constant.

between two charges.

Constant.

No. Very different. Seems even to have a discrete nature, completely
"turning off" beyond a certain distance.

What is the distance betwenn twon Protons in a Nucleus?

Classical size measurements make no sense at that scale. We can
establish a "size" for the various nucleii, and we know the "size" of
protons and neutrons, but "distance" does not necessarily follow.

What is the technique to know whats going in
between Nucleus and to measure Nuclear force?

Smash it, and see what (and how fast) stuff comes out. Add stuff, and
see what (and how fast) stuff comes out.

Usually called the "strong force" or the "strong nuclear force". There
is also a "weak nuclear force".

The corresponding potential for gravity is V ~ -1/r. In classical
field theory, force is the gradient of potential.

I believe that the Yukawa potential is considered a good
model for the strong force:
http://en.wikipedia.org/wiki/Yukawa_potential

Does Nuclear Force which joins protons & nutrons is also proportional

For short distances. The Yukawa potential has a term
exp(-r/constant) in the numerator. The constant is equal
to h-bar/(m*c) where m is the mass of the mediating particle.
The constant is called the "range" of the potential. For
distances less than the range, it looks like a 1/r^2 force.
For distances greater than the range, it is much weaker
than a 1/r^2 force.

What is the distance betwenn twon Protons in a Nucleus?

On the order of 10^-15 m.

Throwing particles at each other in accelerators.

A neutron standard, 80 years out of date, NBS-1 at the National
Institute of Standards and Technology, NIST is used to determine the
constitiuent particles binding energy. ANd nuclear force was so born.

The problem, the standard was cooked and the number of neutrons
released in a single fission is a definitive singe number.
It is all alternative nostatistical interaction theory inside the
fencelines.

It is tough, real tough to measure neutron standard output without
relying on binding energy or crosssections. SO hard they are afraid
to do a true re-calibration for fear they screw-up the security system
in place. It is an old archane nuclear security system, doa. now.

Right now it is a political toss-up, whether to stay on-course or
update theory. It is doa.

[I'm answering in the theoretical context of the standard model,
specifically quantum chromodynamics (QCD). I am not expert in this, so I
don't go into details.]

That is only an approximation. The nucleus of an atom with A1 is not
really made up of individual nucleons, because this is a quantum system
and the nucleons don't really have individual identities -- indeed the
number of particles in a given nucleus is not a good quantum number
(i.e. does not have a definite value).

But the success of the nuclear shell model implies that one can
approximate the nucleus as being made up of nucleons....


What is the Equation of Nuclear Force that joins Protons & Nutrons

Far too complicated to post here. QCD has a Lagrangian that would
require many lines of ASCII text. That must be differentiated to obtain
"force", but that is essentially meaningless for such a QUANTUM system.


Just like Gravitational force is ~ 1/(r^2) where r distance between
two masses.

That is a CLASSICAL system. Moreover, that is from Newtonian mechanics
with is merely an approximation to our current best theory of
gravitation, General Relativity. In GR one cannot write down an equation
for "gravitational force" (one can only write down an APPROXIMATION).


Does Nuclear Force which joins protons & nutrons is also proportional
to square of distance between them?

Not really, it's MUCH more complicated than that. For instance, one
cannot even discuss "nuclear force between this proton and that neutron"
because neither of them has a definite identity and "this" does not apply.


What is the distance betwenn twon Protons in a Nucleus?

Again, the question does not really make sense. But the diameter of a
nuclueus is typically a few fm (10^-15 m), depending on the atomic
number A, and scaling roughly as A^0.33.

Perform electron-nucleus scattering and analyze the results using a
model of the nucleus and a model of the interactions between electrons
and the nucleus (or its components). This is quite complicated....
