Both are examples of static electricity generation. The big difference is the way the electricity is generated.
when glass rod is rubbed with silk cloth it acquires positive charge .
None. Glass is not a conductor. Glass is an insulator.
A Static Charge
It becomes positively charged
One is a negative static charge, the other positive. The exact charge depends on how long and how vigorous the rubbing is. teehee
electrons are transferred from glass to rubber
A plastic ruler is rubbed vigorously with a woolen cloth
it flies up to the glass
Nothing would happen
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.
One is a negative static charge, the other positive. The exact charge depends on how long and how vigorous the rubbing is. teehee
both get charged but with charges of opposite nature
The silk picked up positive charges.
If charge on the balloon is induced due to the charge of the glass rod then there will be opposite charge and so balloon gets attracted by the rod. Unlike charges do attract each other
anything can be rubbed its a matter of the transfer of electrons
electrons are transferred from glass to rubber
A plastic ruler is rubbed vigorously with a woolen cloth
it flies up to the glass
The Physicist who said first that the charge on a glass rod rubbed with silk is positive was Michael Faraday.
The balloon will be attracted to the rod.
the silk will rub of the electrons on the silk, leaving the glass positively charged
