Expert Solution

Step 1
When a glass rod is rubbed with silk, some of the electrons are removed from the glass rod and it gets positively charged. However, a metallic substance like steel cannot be charged by rubbing. The redistribution of electrons takes place in the metal lattice and makes it electrically neutral when we try charging by friction.
