How does an alpha particle get attracted by nuclear forces of the nucleus of an atom (although having the same charge) when it is very close to the nucleus?

 Alpha particles are positively charged particles that are made up of two protons and two neutrons. They are produced in nuclear reactions, such as those that occur during radioactive decay. The positive charge of an alpha particle is the same as that of a nucleus, meaning that it is attracted to the nucleus of an atom when it is close by. 

At the atomic level, the nucleus of an atom is composed of protons and neutrons, which are held together by the strong nuclear force. This force is a nuclear force which operates at very short distances and is much stronger than the electromagnetic force that holds together negatively charged electrons and positively charged protons. The strong nuclear force is an attractive force that acts between protons and neutrons and is responsible for binding them together in the nucleus. It is this strong nuclear force that holds the nucleus together, and it is also this force that can attract an alpha particle to the nucleus of an atom when it is close by. 

When an alpha particle is close to the nucleus, the strong nuclear force will cause the protons and neutrons in the alpha particle to interact with the protons and neutrons in the nucleus. This interaction increases the attraction between the alpha particle and the nucleus. As the alpha particle and the nucleus get closer together, the strong nuclear force increases and the attraction between the alpha particle and the nucleus becomes stronger. This attraction is powerful enough to overcome the repulsive forces of the alpha particle's positive charge and the nucleus's positive charge, and the alpha particle will be drawn towards the nucleus. 

The strong nuclear force is an incredibly powerful force and is capable of overcoming the repulsive electromagnetic force between two positively charged particles. As an alpha particle gets closer to the nucleus, the attraction between the two increases and the alpha particle is drawn in. This same process also applies to other particles, such as protons and neutrons, that have the same charge as the nucleus. 

The strong nuclear force is the primary force that attracts an alpha particle to the nucleus when it is very close. It is an incredibly powerful force and is capable of overcoming the repulsive electromagnetic force between two positively charged particles. As an alpha particle gets closer to the nucleus, the attraction between the two increases and the alpha particle is drawn in. This same process also applies to other particles, such as protons and neutrons, that have the same charge as the nucleus. 

The attraction between an alpha particle and the nucleus of an atom is an example of a nuclear force. This is a powerful force that operates at very short distances and is much stronger than the electromagnetic force that holds together negatively charged electrons and positively charged protons. The strong nuclear force is an attractive force that acts between protons and neutrons and is responsible for binding them together in the nucleus. It is this strong nuclear force that holds the nucleus together, and it is also this force that can attract an alpha particle to the nucleus of an atom when it is close by. 

In conclusion, the strong nuclear force is the primary force that attracts an alpha particle to the nucleus when it is very close. This force is much stronger than the electromagnetic force and is capable of overcoming the repulsive forces of the alpha particle's positive charge and the nucleus's positive charge. As an alpha particle gets closer to the nucleus, the attraction between the two increases and the alpha particle is drawn in. This same process also applies to other particles, such as protons and neutrons, that have the same charge as the nucleus.
