When a metal rod is rubbed with wool, it gets energized because the metal rod and wool both have opposite effects.
the rod slightly attract each other
Not sure about a Peace of fur but when it is rubbed with a piece of fur you will get static electricity building up on the rod.
The iron rod becomes shinier and the wool cloth wears out. If you rub the same wool cloth on a hard rubber rod, the rod will become charged with static electricity and you will be able to pick up small bits of paper with it---whoopee!
The plastic rod gains static electricity.
the rod slightly attract each other
no
real good
It is static electricity.
it attracts it
what change will take place if two same materials are rubbed over each other
Nothing would happen
Equal amount of positive charge in the woolReason: Just before rubbing both rod and wool are neutral. Now as we rub the rod with wool then loosely bound electrons get migrated right from wool to the rod. So rod gets excess electrons and balance between equal positive and negative goes off. So it gets negatively charged. If so then wool as it has lost electrons right from balancing it has to be positively charged
