What does it mean when the electroscope leaves move apart?

DETERMINING CHARGE WITH AN ELECTROSCOPE The negative charge of the rod will repel electrons away from the electroscope and they will flow into your body. When you remove your hand and the charged rod, the leaves spread apart, indicating a positive charge has been achieved due to the loss of electrons.

What happens when you touch a charged electroscope?

When the positively charged electroscope is touched, its charge becomes grounded (or neutralized). The negatively charged electrons enter the electroscope and neutralize the positive charge. As the electroscope loses its charge, the needle relaxes back to its naturally upright position.

Why do the leaves of the charged electroscope move farther apart if a rod with the same charge is brought near?

The leaves spread apart because the excess electrons in one leaf repel the excess electrons in the other leaf. Due to the loss of electrons from the knob, the knob is now positive. When the rod is removed from the vicinity, diagram 3, the electrons return to the knob and the electroscope is as it was before – neutral.

When a rod is brought near a neutral electroscope the leaves move apart Which statement best describes the charge on the rod?

Question: When a rod is brought near a neutral electroscope, the leaves diverge. Which statement best describes the charge on the rod? It may be positive or negative.

When an electroscope is charged the leaves rise to a certain angle and remain at that angle Why do they not rise further?

Note that leaves in the electroscope will rise farther if charge on the electroscope is greater, but electrostatic force between the leaves will balance itself with gravitational pull, but at a higher angle.

What happens in 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.

How does an electroscope work?

The working principle of an electroscope is based on the atomic structure of elements, charge induction, the internal structure of metal elements and the idea that like charges repel each other while unlike charges attract each other. When no charge is present the metals leaves hang loosely downward.

What induced charge separation?

Charge-induced separation occurs when a charged object is brought close to a neutral one. The charges inside of the neutral object of the same polarity as the charged object will be repelled while charges of the opposite polarity will be attracted to it.

What is different about electron flow when charging the electroscope positively what causes the leaves to repel each other in this case?

When a positively charged object is brought near the electroscope (Fig. 6), negative charges in the metal of the scope move toward the positive object, causing the leaves to have a positive charge, and the leaves repel each other. The stronger the charge, the greater the separation of the leaves.

What happens to the leaves of an electroscope when no charge is present?

In the case of the uncharged electroscope, i.e., when no charge is present, the metal leaves hang straight down. However, when a charged object is brought near the knob of the rod, or we can say the electroscope, the electric charge travels down through the rod and spreads the leaves apart.

Why does an electroscope have different types of charges?

They can have different types of charges, but amount of negative charge must be larger than the amount of positive charge to repel electrons from top of the electroscope to the leaves. Look at the given picture; when we put a charged conductor sphere into the neutral hollow, it is charged by induction.

What makes an object close to an electroscope?

This decrease in the number of electrons makes them close. To sum up; when you bring charged object closer to the charged electroscope. · If the leaves rise then both the rod and electroscope have same charge. · But if the leaves are closed than charges of electroscope and rod are opposite.

How are the plates of an electroscope different?

Both of the plates can be positively charged and have different amounts of charges. They both attract electrons of the leaves. 2. They can have different charges; however, amount of positive charge must be larger than the negative charge. Since, there must be net positive charge to attract electrons from the leaves.
