Why do the leaves of an electroscope repel each other when a charged object touches the knob?
Because when the charged object is say, negatively charged, the electrons in the electroscope want to get as far away as possible from the negative object because "like" charges REPEL. so when the electrons in the electroscope move to the leaves , they now are both negative and "like" charges so now the leaves want to get away from each other as well and that's why they separate.

How do you use the gold leaf electroscope?
Touch an object to the metal receiver at the top of the electroscope. If the object is charged, it will transfer its charge to the electroscope. The receiver is connected to the gold leaf, so the electric charge from the object will spread throughout the metallic parts of the electroscope, including the suspended gold leaf. The two halves of the leaf then have the same type of charge on them. Since like charges repel, the leaves levitate away from each other at an angle dependent upon how much charge they hold.
What happens with electrons when objects become positively or negatively charged?
When an object becomes positively charged, it has lost electrons, resulting in an excess of positive charge. When an object becomes negatively charged, it has gained electrons, resulting in an excess of negative charge. Electrons are responsible for carrying the electrical charge in objects that can become charged.
How do you find charge of an unknown material that either they positively charged or not?
Tie the unknown object and an object with a known charge to separate strings. Hold the two objects up by the strings, and bring them near each other. If the objects repel it means that the unknown object has the same charge as the known object. If they attract it means the unknown object has an opposite charge as the known object.
Transfering charge by touching is charging by?
Transfer of charge by touching is known as charging by conduction. When a charged object touches a neutral object, electrons are transferred between the two objects until they reach equilibrium, resulting in both objects being charged.
An electrically neutral object can be attracted by a positively charged object because?
A neutral pith ball is still "charged", it just doesn't display excessively charged behavior. Since it is neutral, having nearly equal positive and negative charge, the proximity of the positively charged pith ball still attracts the negative charge present in the ball, inducing polarization moving the ball closer to the positively charged one. Once they make contact, the conductibility of the pith ball quickly accepts excess charge from the other, creating a like charge repulsion.
Why do the leaves of an electroscope spead apart when a charged object touches the metal knob?
When a charged object touches the metal knob of an electroscope, electrons are either transferred to or from the electroscope. This results in an imbalance of charge between the metal knob and the leaves, causing them to repel each other due to the like charges. The leaves spreading apart is a visual indication of the presence of charge on the electroscope.
Why do the leaves of an electrictroscope spread apart when a charged object touches the metal object?
When a charged object touches the metal knob of an electroscope, electrons are either transferred to or from the electroscope, causing the metal leaves to gain a net charge. Like charges repel each other, so the leaves spread apart due to the repulsion between the negatively charged leaves. This spreading apart indicates the presence of an electric charge on the electroscope.
Explain with suitable diagrams how an electroscope responds when the knob touches a positively charged object?
When the knob of the electroscope touches a positively charged object, electrons from the object are transferred to the electroscope, causing it to become positively charged. This causes the gold leaves to repel each other due to the like charges, spreading apart and indicating the presence of a positive charge on the electroscope. A diagram would show the initial position of the gold leaves close together, then spreading apart when the electroscope becomes positively charged.
How can you tell that an electroscope is charged?
You can tell that an electroscope is charged by observing the divergence of the leaves. If the leaves spread apart after bringing a charged object close to the electroscope, it indicates that the electroscope has acquired a charge.
How would you ue an electroscope tofindout whether an object is charged or no?
To use an electroscope to determine if an object is charged, first discharge the electroscope by grounding it. Next, bring the object close to the electroscope without touching it. If the leaves of the electroscope diverge, it indicates that the object is charged.
How can you tell the difference between a positively charged object and a negativly charged object by using an electroscope?
A positively charged object will cause the leaves of the electroscope to separate or diverge. A negatively charged object will cause the leaves to come together or converge.
Why do the leaves of an electroscope repel each other when a charged object touches a metal knob?
Because when the charged object is say, negatively charged, the electrons in the electroscope want to get as far away as possible from the negative object because "like" charges REPEL. so when the electrons in the electroscope move to the leaves , they now are both negative and "like" charges so now the leaves want to get away from each other as well and that's why they separate.
Why do the leaves of an electroscope repel each other when a charged objects touchers the metal knob?
When a charged object touches the metal knob of an electroscope, it transfers some of its charge to the electroscope, causing the leaves to acquire the same charge. Like charges repel each other, so the leaves spread apart from each other due to the repulsive force. This demonstrates the presence of excess charge on the electroscope.
How is an electroscope is charged by friction?
An electroscope can be charged by friction through the process of rubbing a charged object, such as a glass rod or a piece of fur, against the top metal cap of the electroscope. This transfers some of the charge from the object to the electroscope, causing a redistribution of charges within the electroscope's metal leaves.
What would you use to see if somthing is charged?
You can use an electroscope to see if something is charged. When a charged object is brought near the electroscope, the leaves of the electroscope will either repel or attract each other, indicating the presence of a charge.
How do you test for static charge by Electroscope?
To test for static charge, first discharge the electroscope by touching the metal knob with your hand. Next, bring the object you want to test close to the electroscope's top plate. If the object is charged, the electroscope will show a corresponding deflection of the metal leaves. If the leaves move apart, the object is positively charged. If they move together, the object is negatively charged.
How do you charge an electroscope?
by induction
