In mechanics, we often use centre of centre of mass,but, I have never found anywhere to consider centre of charge even in problems of symmetrical charge distribution.Where is the difference of the two subjects?

The centre of gravity is the point at which the weight of an object can be considered to act. It is the point where the mass of an object is evenly distributed, meaning that it will not tip or fall in any direction.
The centre of gravity is calculated by finding the weighted average of all the individual points of mass in an object. This can be done by dividing the total torque (force x distance) by the total weight of the object.
The centre of gravity is important because it affects the stability and balance of an object. If an object's centre of gravity is too high or too low, it can cause it to tip or fall over. It is also important in determining how an object will behave when subjected to external forces, such as gravity or acceleration.
The centre of gravity and centre of mass are often used interchangeably, but there is a subtle difference between the two. The centre of gravity refers to the point where the weight of an object is evenly distributed, while the centre of mass refers to the point where the mass of an object is evenly distributed. In most cases, they are located at the same point, but in some cases where there is a varying gravitational field, they may differ.
The centre of charge is the point at which the total electrical charge of an object is considered to be concentrated. It is similar to the centre of gravity, but instead of weight, it takes into account the electrical charge of an object. It is an important concept in electrostatics and can be calculated in a similar manner to the centre of gravity.
