The attraction between the paper and the perspex ruler is due to static electricity. When the ruler is rubbed against the paper, electrons are transferred between the two materials, creating a temporary positive and negative charge that causes them to be attracted to each other.

What happens if a perspex rod is rubbed to a piece of paper instead of a polythene rod?
Rubbing a perspex rod against a piece of paper will likely transfer some electrons from the perspex to the paper, causing the perspex rod to become positively charged and the paper to become negatively charged. This can create an electrostatic attraction between the rod and the paper.
Why does a charged ruler attract small pieces of paper?
A charged ruler attracts small pieces of paper due to the electrical force between the charges. The ruler becomes charged when electrons are transferred to or from it, creating an electric field around it that exerts a force on the neutral pieces of paper, causing them to be attracted to the ruler.
Is plastic ruler gets attracted towards pieces of paper when rubbed with oily hair?
Yes, when a plastic ruler is rubbed with oily hair, it can become statically charged. This static charge may attract lightweight objects like pieces of paper due to the electrostatic force between the ruler and the paper.
Why does plastic ruler that has been rubbed with cloth have the ability to pick up small pieces of paper Why is this difficult to do in humid day?
When a plastic ruler is rubbed with cloth, it becomes charged with static electricity. This static charge attracts small pieces of paper due to the phenomenon of electrostatic attraction. On a humid day, the moisture in the air can dissipate the static charge more quickly, making it harder for the ruler to pick up the paper.
How could a sheet of paper keep the ruler from moving?
Placing a sheet of paper under the ruler increases the friction between the ruler and the surface it is resting on, preventing it from easily sliding or moving. The paper creates more resistance, making it harder for the ruler to shift position.
What happens if a perspex rod is rubbed to a piece of paper instead of a polythene rod?
Rubbing a perspex rod against a piece of paper will likely transfer some electrons from the perspex to the paper, causing the perspex rod to become positively charged and the paper to become negatively charged. This can create an electrostatic attraction between the rod and the paper.
Why does a charged ruler attract small pieces of paper?
A charged ruler attracts small pieces of paper due to the electrical force between the charges. The ruler becomes charged when electrons are transferred to or from it, creating an electric field around it that exerts a force on the neutral pieces of paper, causing them to be attracted to the ruler.
What is a graph paper ruler?
A WOOD RULER A STONE RULER A IRON RULER A DIAMOND RULER A EMERALD RULER

What are facts about perspex?
perspex is a plastic
When was Perspex Island created?
Perspex Island was created in 1991.
When you put a piece of paper on a ruler then hit the ruler how come the paper doesnt fly into the air?
This is because of the atmospheric pressure exerting a downward force on the paper.
How could a sheet of paper keep the ruler from moving?
Placing a sheet of paper under the ruler increases the friction between the ruler and the surface it is resting on, preventing it from easily sliding or moving. The paper creates more resistance, making it harder for the ruler to shift position.
Which is cheaper glass or perspex?
Perspex is cheaper. 100%. Defo. IRL.
Is perspex a soft solid?
Perspex (PMMA) is not a soft solid.
What are the properties of perspex?
E=2800 MPa nu=0.38 For Perspex sheet
