Nothing. perhaps it gets a little cleaner but there will be no electrostatic effect.
no
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!
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.
Nothing would happen
what change will take place if two same materials are rubbed over each other
Nothing. perhaps it gets a little cleaner but there will be no electrostatic effect.
There is a very big difference between the electrical charge of a balloon rubbed in a person's hair and a glass rod rubbed with silk. The charge from the balloon will just make it stick to objects. The charge from the glass rod will emit a very large electrical shock that might knock a person to the ground. This is because the glass rod is a better conductor of electricity than the balloon.
no
When a metal rod is rubbed with wool, it gets energized because the metal rod and wool both have opposite effects.

it attracts it

One is a negative static charge, the other positive. The exact charge depends on how long and how vigorous the rubbing is. teehee
Both are examples of static electricity generation. The big difference is the way the electricity is generated.
The balloon will be attracted to the rod.
