When straw is rubbed with paper it acquires charge due to friction. This straw when brought near uncharged straw induces opposite charge in the region of the uncharged straw nearer 2 the charged one. Then as the law is, unlike charges attract.

Why does a straw attract another straw when rubbed with piece of paper but repels it if it is rubbed with a sheet of paper?

When a straw is rubbed with a piece of paper, it acquires a positive charge due to the transfer of electrons from the paper. Two positively charged straws will repel each other. However, when a straw is rubbed with a sheet of paper, it acquires a negative charge, and opposite charges attract, resulting in the straws being attracted to each other.


What happens when a straw is rubbed with a sheet of paper?

When a straw is rubbed with a sheet of paper, friction causes electrons to transfer between the two materials. The straw becomes negatively charged as it gains electrons, while the paper becomes positively charged as it loses electrons. This can result in the two objects attracting or repelling each other.


What happens when a straw is rubbed with your body?

Rubbing a straw against your body transfers electrons from your body to the straw, giving the straw a net negative charge due to an excess of electrons. This charge imbalance can cause the straw to attract lightweight objects like small pieces of paper or dust.

The straw moved due to the attraction of opposite electrical charges. Rubbing the stirring rod created a build-up of static electricity, which then interacted with the charged particles in the straw, causing it to move.
