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.

Is there anything more powerful than an electron microscope?

 Yes, there are several technologies that are more powerful than an electron microscope. Some of the most powerful microscopes in the world are capable of magnifying specimens up to 10 million times their original size, which is far beyond the capabilities of an electron microscope.

The most powerful microscope in the world is the Scanning Transmission Electron Microscope (STEM). It uses a beam of electrons to create a highly detailed image of a specimen, which can be magnified up to 10 million times the original size. This type of microscope is used to study extremely small features, such as individual atoms, and is capable of resolving features smaller than 0.1 nanometer.

Another powerful microscope is the Scanning Tunneling Microscope (STM). This microscope uses a probe to measure the electrical current at the surface of a specimen. By doing this, it can create a topographical map of the specimen, and can magnify up to 100 million times. This type of microscope is very useful for studying areas of a specimen that are too small to be seen with an electron microscope.

The Atomic Force Microscope (AFM) is another powerful microscope, which is capable of magnifying samples up to 1 billion times their original size. This type of microscope uses a probe to measure the surface of a specimen, and can be used to study very small features, such as individual molecules.

The most powerful microscope in the world is the Helium Ion Microscope (HIM). This microscope uses a beam of helium ions to create a highly detailed image of a specimen, and can magnify up to 1 trillion times the original size. This type of microscope is used to study extremely small features, such as individual atoms.

These are just a few of the technologies that are more powerful than an electron microscope. There are many more powerful microscopes in the world, such as the X-ray microscope, the infrared microscope, and the ultraviolet microscope, which are all capable of magnifying samples up to different levels, depending on the type of microscope used. As technology continues to advance, more powerful microscopes will be developed, allowing us to study even smaller features.
