As a result of friction against the silk, a positive charge was imparted to the glass rod. Explain if all the atoms that make up a charged glass rod are neutral? Why? Has the mass of the glass rod changed after giving it a positive charge? How? Why?
No, some of the atoms that make up the glass rod will turn into positive ions as a result of electrification, and therefore they no longer retain their electroneutrality. The mass will change, but this change will be very insignificant, because the mass of the electrons, which, when rubbed, pass from the rod to the silk, is small compared to the mass of the atom.
