How does a rubber rod become negatively charged through friction?
It is rubbed with another object, and electrons move onto the rod
. … A charged object touches a neutral object.
How does a rubber rod become negatively charged through friction?
How does a rubber rod become negatively charged through friction? …
It touches a positively charged object, and electrons move onto the rod
. It is rubbed with another object, and electrons move onto the rod. It is rubbed with another object, and protons move off of the rod.
Why did the rod becomes negatively charged?
When a polythene rod is rubbed with a duster,
the friction causes electrons to gain energy
. Electrons gain enough energy to leave the atom and ‘rub off’ onto the polythene rod. The polythene rod has gained electrons, giving it a negative charge.
When a rubber rod is rubbed with fur the rubber rod becomes negatively charged thus it can be concluded that?
| A B | How is a positive charge usually given to a neutral object? electrons are removed from the object. | When a rubber rod is rubbed with fur, the rod becomes negatively charged due to the transfer of electrons to the rod |
|---|
When a rubber rod is rubbed with wool the rod becomes negatively charged what can you conclude about the wool’s charge after the rubbing process Why?
When the wool and the rubber are rubbed,
a certain amount of electrons passes from the wool to the rubber
, so the rod acquires an excess of charge negative. In the same way, the wool will have uncompensated protons, which give the wool a positive charge.
What charge does the rod have positive or negative?
56.06 — Electrostatically charged rods. When you rub the plastic rod (polyethylene terephthalate, glycol modified, or PETG) with the wool cloth, the
rod charges negative
. When you rub the glass rod with the silk, the rod charges positive.
Why is paper attracted to a charged rod?
A positively charged rod is brought near a piece of paper. … When the positively charged rod is brought near the neutral paper,
it induces a negative charge on the side of the paper nearer to the rod
. Since unlike charges attract each other, the paper will be attracted to the rod.
What happens when a rubber rod is rubbed with fur?
When a rubber rod is rubbed with fur or felt electrons are transferred from
the material to the rod
, giving the rod a negative charge. Two negatively charged objects repel. When a positively charged object is brought near a negatively charged object the two objects attract one another.
What did Millikan’s oil drop experiment prove?
In 1909, Robert Millikan
What is the name of the area around a charged object?
An electric field
is a region around a charged object where the object’s electric force is exerted on other charged objects. Electric fields get weaker the farther away they are from the charge. An electric field is invisible. You can use the field line to represent it.
What happens if a glass rod is rubbed with silk?
A glass rod
becomes positively charged
when rubbed with silk, while the silk becomes negatively charged.
Why are you more likely to get a static shock to your finger than to your whole hand?
Explain why you’re more likely to get a shock from static electricity by touching a metal object with your finger instead of with your entire hand. How are conductors different from insulators? … Because of a higher moisture content, air is a better conductor of charge in the summer than in the winter.
When a plastic rod is rubbed with wool the wool becomes positively charged because?
| A B | When a plastic rod is rubbed with wool, the wool acquires a positive charge because electrons are transferred from the wool to the rod. | How is a positive charge usually given to a neutral object? electrons are removed from the object. |

What happens when a negative rod touches an Electroscope?
When the negatively-charged rod is brought close to the electroscope,
positive charges are attracted to it and negative charges are repelled away from it
. … The electroscope has a net neutral charge and the rubber rod has a net negative charge. If they are brought into contact, they will both take a net negative charge.
When a glass rod is rubbed with rubber the rod becomes positively charged This is because?
On rubbing together, the glass rod loses 2 electrons and silk gains 2 electrons. Now the glass
rod has 8 electrons and 10 protons
which makes it positively charged.
What happens when you rub a metal rod with a cloth?
Dissimilar objects have different affinities for electrons. When two such objects, initially neutral, are rubbed together, the friction may cause electrons to pass from one to the other. … Rubbing a metal rod with a wool cloth
can also transfer electrons
.
