Not all objects became electrified, objects "electrified" by the same machine appeared to repel each other (like magnets of the same charge); and objects "electrified" in different ways (one by touching an electric machine, for example, and the other, say, by rubbing amber) would attract each other (like magnets of opposite charge).
repel
It means something that will stick to other objects.
cancer and many other disease
they repel each other
It's due to static electricity build up. The balloons have become charged with electricity and it is the same charge on both balloons (either positive or negative). Opposite charges attract, identical charges repel each other.

Friction
Pass two objects against each other to create friction.
when the two objects are rubbed,certain other object are attract to them.

It was the Eurasian Plate and the North american plates that caused the volcano to erupt. They rubbed against each other and caused shaking
when amber is rubbed with silk cloth +ve charge comes on silk cloth and -ve on amber due to interaction between their molecules, so is that when we comb our hairs , then -ve charge comes on comb and +ve on hairs,so when we bring silk cloth near the comb they attract each other due to 'ving opposite charges

Electric comes from the Latin word electrum "amber," from Greek elektron "amber".Originally the word described substances which, like amber, attract other substances when rubbed. Electric means charged with electricity and is from 1670s. The physical force was called this because it was first generated by rubbing amber.

The early Germans called this Baltic amber by the name of 'Bernstein', due to the sweet smell it emitted when burnt. The Greeks called it 'Elektron' due to its properties of developing static electricity when rubbed. Amber is known as 'Kerba' in the local markets in India.
objects can be negatively charged when it is rubbed with another object; a woolen cloth for example. this is because the electrons from the woolen cloth will be transferred to the object which is being rubbed! only electrons can be transferred to the object and make the object becomes negatively charged.
