A plastic ruler is rubbed vigorously with a woolen cloth
The plastic rod gains static electricity.
Both rods acquired charge of the same polarity during the rubbing process, so there will be a force of repulsion between them.
Because electrons will be transferred from the cloth to the insulating rod. But the charge will be negative.
Silk Cloth

Rubbing a plastic body like comb on dry hair can impart static charges on it. Also, glass rod rubbed on silk cloth, ebonite rod rubbed on silk cloth. Most of them we have learnt in our schools. If you want a something really huge, try Van de Graaff generator.

Both get charges oppositely. So they would attract each other if we bring them closer
The polythene becomes negatively charged.
Yes, it will because of the negative and positive charges which are on the objects, the rod will pick the small pieces of paper up.
A it has a electron
When glass rod is rubbed with silk cloth it becomes positively charged and the silk cloth becomes negatively charged. This is because the glass rod looses electrons to the silk cloth which makes it positive and the silk cloth becomes negative.
