Question

Стеклянную палочку наэлектризовали,и её заряд стал равным 6,4*10^-9.Что произошло с массой палочки?

Answer 1

Масса уменьшилась на 3.6×10^-20 кг.

Answer 2

The electrization of the glass rod and its charge

The question asks about what happened to the mass of a glass rod after it was electrized and its charge became equal to 6.4*10^-9.

The mass of the glass rod would not have changed at all. Electrization is the process of imparting an electric charge to an object by friction, without changing the object's mass. When the glass rod was rubbed and its charge became equal to 6.4*10^-9 Coulombs, its mass remained the same at 9.1*10^-31 kilograms The charge on the rod is related to the number of excess or missing electrons on its surface, but does not affect the number of protons and neutrons that make up its atomic structure and mass. Therefore, the mass of the electrized glass rod stayed the same after gaining the electric charge.
