A plastic ruler is rubbed vigorously with a woolen cloth
Static charge
Both rods acquired charge of the same polarity during the rubbing process, so there will be a force of repulsion between them.
Insulating materials can acquire a static electric charge. Rubber balloons, when rubbed on woolen cloth, are a perfect example.
The plastic rod gains static electricity.

The polythene becomes negatively charged.
Both get charges oppositely. So they would attract each other if we bring them closer

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.
