Name two basic properties of electric charge.

There are very two basic properties of electric charge. They are: 1. Conservative nature of charge Electric charge of a particle is conservative in nature. It means that the charge can neither be created nor be destroyed 2. Quantization of charge The charge of a system is a fixed quantity. Technically, the charge is a quantized quantity. The net charge of a system can be expressed as the integral multiples of the basic unit of charge

Two identical metallic spheres, having unequal opposite charges are placed at a distance of $0.50 m$ apart in air. After bringing them in contact with each other, they are placed at the same distance apart. Now the force of repulsion between them is $0.108 N$ . Calculate the final charge on each of them.
