Answer:
Explanation:
From the question we are told that
Nucleus diameter
a 12C nucleus
Required kinetic energy
Generally initial speed of proton must be determined,applying the law of conservation of energy we have
where
=initial kinetic energy
=final kinetic energy
=initial electric potential
=final electric potential
mathematically
where
=distance b/w charges
=nucleus charge
=constant
=proton charge
Generally kinetic energy is know as
Therefore
Generally equation for radius is
Mathematically solving for radius of nucleus
Generally we can easily solving mathematically substitute into v_1
Therefore the proton must be fired out with a speed of
