When a rubber rod is rubbed with wool the rod becomes negatively charged?

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

How does a object become negatively charged?
if some of the positive charges have been either chemically removed or bonded together, that is how they become negatively charged...................... xoxo
Why does a glass rod get positively charged when rubbed with rubber?
electrons are transferred from glass to rubber
Can an insulator be charged?
Insulating materials can acquire a static electric charge. Rubber balloons, when rubbed on woolen cloth, are a perfect example.
Why a balloon now negatively charged?
When you rub a balloon onto your hair or piece of clothing, the balloon collects the electrons (negative charge) from the hair or clothing you rubbed it on. The balloon now has more electrons (negative charge) than protons (positive charge) making it have a negative charge. The hair or clothing has more protons than electrons making it have a positive charge.
What happens when iron rod rubbed with wool cloth?
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!

If electrons are rubbed from cat's fur onto a rubber rod does the cats fur become positively or negatively charged?
Positively charged,because electrons are negatively charged and when you remove them only protons remain and those are positively charged,what makes the fur positively charged as well.
What is the Effect of rubbing glass with silk rubber?
on rubbing glass with silk, the former one becomes positively charged whereas the other negatively charged.
Why does a glass rod get positively charged when rubbed with rubber?
electrons are transferred from glass to rubber
What happens when a hard rubber ball is rubbed by wool?
Rubbing wool on the ball transfers electrons (negatively charged) from the wool to the ball. The excess charge builds up and produces static electricity.
When a rubber rod is rubbed with wool the rod becomes negatively charged. what can you conclude about the magnitude of the wool's charge after the rubbing process?

What keep you from getting shock in a car by lightning?
lightning is caused when the really negatively charged clouds want to get rid of the charge and so the negatively charged electrons jump from the clouds to the nuetrally charged earth, if it was to strike you car it won't get shocked because the tyres are made of non-conductive rubber,
Why do electrician screwdrivers have rubber handle?
This is my opinion. When using a screwdriver, you would have to twist and turn. This creates friction. by creating friction, the screwdrivers are getting negatively charged. But, rubbers are insulators(objects that hold elections loosely. Mostly non-metals). this means that rubber can hold electrons tightly; preventing any electrons from flowing. So by using rubber, electricians or one would have protection from electric shock. but if there were no rubber, there would be sparks from negatively charged screwdriver when it is attracted to a positive charged or neutral object. The rubber hold the electrons which prevent electric shock. ~Anonymous
