A plastic ruler typically does not have a charge as it is an insulator and does not conduct electricity. If a ruler were to become charged, it would likely carry a small amount of static electricity, which could be either positive or negative depending on the materials it has come into contact with.
What else can I help you with?
If a plastic ruler is rubbed with a cloth does the ruler obtain a positive charge?
Because electrons will be transferred from the cloth to the insulating rod. But the charge will be negative.
Why is it difficult to do on humid day a plastic ruler that has been rubbed with cloth have the ability to pick up small pieces of paper?
On a humid day, the air is more saturated with moisture, making it harder for objects to build up an electrostatic charge, as the moisture helps to dissipate the charge. When a plastic ruler is rubbed with cloth, it gains a negative static charge that allows it to attract small pieces of paper that are neutrally charged. The moisture in the air reduces the effectiveness of the ruler’s static charge, making it more difficult to pick up the paper.
What will happen if a glass ruler is rubbed vigorously on a woolen cloth?
Rubbing a glass ruler on a woolen cloth will create a static charge on the ruler due to the triboelectric effect, where electrons transfer between the materials. The glass ruler will become negatively charged as it gains electrons from the woolen cloth, resulting in static attraction to objects with a positive charge.
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.
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.
If a plastic ruler is rubbed with a cloth does the ruler obtain a positive charge?
Because electrons will be transferred from the cloth to the insulating rod. But the charge will be negative.

Is a ruler a conductor of electricity?
Plastic is generally used as an insulator. A plastic ruler would not be a conductor of electricity.

What is a acrylic ruler?
It's a ruler made of acrylic. Essentially, it's a clear plastic ruler.
How much does a plastic 30cm ruler weigh?
20g
Why a ruller will attract pieces of papers?
when you rub the plastic ruler on e.g. a yellow duster it takes the electrons (which is the negative charge) from the yellow duster and the plastic ruler becomes negatively charged. The paper has both protons and electrons the protons are positively charged. and very much like a magnet the negative is attracted to the positive hence the paper sticks to the ruler Hastings Tarrant
What is a ruler with no markings called?
a bit of plastic
Why is a metal ruler stronger than a plastic ruler by terms of the kinetic theory?
A metal ruler is stronger than a plastic ruler in terms of the kinetic theory because the metal atoms are arranged in a tightly packed, orderly structure which gives it greater strength and cohesion. The metal ruler's atomic structure allows it to better withstand external forces and deformation compared to the more loosely arranged atoms in a plastic ruler.
How many grams does a plastic ruler weigh?
A plastic ruler typically weighs around 5-10 grams, depending on its size and thickness.
