A glass rod is rubbed with a silk cloth and an inflated rubber balloon is rubbed with a woollen cloth.
Now, out of glass rod, silk cloth, rubber balloon and woollen cloth:
(a) Which two objects acquire negative charge?
(b) Which two objects acquire positive charge?

Now, out of glass rod, silk cloth, rubber balloon and woollen cloth:

(b) Which two objects acquire positive charge?
When you are rubbing the glass rod with the silk cloth, electrons are stripped away from the atoms in the glass and transferred to the silk cloth. This leaves the glass rod with more positive than negative charge. By adding an “extra” electron. We can now interpret what is happening with the glass/plastic rod experiments. Glass happens to lose electrons easily, and silk grabs them away from the glass atoms, so after rubbing the glass becomes positively charged and the silk becomes negatively charged. When you rub a balloon on wool, this causes the electrons to move from the wool to the balloon's surface. The rubbed part of the balloon now has a negative charge.
