What does it mean when we say "centre of charges coincide"? What is the physical meaning of dipole moment?

To answer this, more context is needed. I can only guess that you there are two or more charge distributions that have a "center of charge" just like mass distributions have a "center of mass". When they coincide, the centers are on top of one another.
The physical meaning is a collection of positive and negative charges such that the sum of positive and negative charges is zero, but the charges are spatially separated. An common example is the water molecule H2O that is neutral (same total number of protons and electrons) but there is spatial separation of these charges. Free dipoles attract each other and this gives them interesting properties. Electric dipole attraction is important in protein folding for example.What is the physical meaning of dipole moment?

The "centre of charges coincide" refers to the point in an electrically neutral system where the positive and negative charges are perfectly balanced, resulting in a net charge of zero. This point is also known as the centre of mass or centre of gravity.
The centre of charges coincide is an important factor in determining the dipole moment of a system. If the centre of charges coincide with the centre of mass, the dipole moment will be zero. However, if the centre of charges does not coincide with the centre of mass, there will be a non-zero dipole moment.
No, the centre of charges coincide is a physical property of a system and cannot be manipulated. It is determined by the distribution of charges within the system.
The dipole moment is calculated by multiplying the distance between the positive and negative charges by the magnitude of the charges. This gives a vector quantity, with direction from the negative charge towards the positive charge.
The dipole moment is a measure of the separation of positive and negative charges in a system. It is an important concept in electromagnetism and is used to calculate the strength of electric fields and the energy of interactions between charges.
