Predict what would happen if you touched the knob of a positively charged electroscope with a negatively charged object?
If you touch the knob of a positively charged electroscope with a negatively charged object, the excess electrons from the negatively charged object will flow to the electroscope, neutralizing the positive charge. The electroscope will become neutral or slightly negatively charged as a result.
What else can I help you with?
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.
How can a negatively charged rod charge an electroscope positively?
When a negatively charged rod approaches an electroscope, it induces a separation of charges within the electroscope. Electrons in the electroscope are repelled by the negative charge of the rod and move to the opposite end of the electroscope, leaving a net positive charge at the top. This gives the electroscope a positive charge, even though the initial influence was negative.
What will happen to a negatively charged rod touches a neutral electroscope?
If a negatively charged rod touches a neutral electroscope, electrons will flow from the rod to the electroscope, causing the electroscope to become negatively charged. The leaves of the electroscope will repel each other, indicating a charge has been introduced.
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.
What would happen if you touched a knob of positivly charged electroscope with another positivel charged object?
If you touch a positively charged object to a positively charged electroscope, the electroscope may become even more positively charged due to the transfer of additional positive charge. This could result in greater divergence of the leaves of the electroscope, indicating a higher level of positive charge on the electroscope as a result of the contact with the positively charged object.
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.
Attraction and repulsion?
Attraction and repulsion, in physics means, is when two objects attract and repel one another. For example, an When a negatively charged rod is brought near an electroscope with negatively charged leaves, the leaves will repel. Same goes for when a positively charged rod is brought near an electroscope with positively charged leaves, the leaves will repel. But if a negatively charged rod is brought near an electroscope with positively charged leaves, the leaves will attract. Kind of like opposites attract, and likeness repels.
How can a negatively charged rod charge an electroscope positively?
When a negatively charged rod approaches an electroscope, it induces a separation of charges within the electroscope. Electrons in the electroscope are repelled by the negative charge of the rod and move to the opposite end of the electroscope, leaving a net positive charge at the top. This gives the electroscope a positive charge, even though the initial influence was negative.
What will happen to a negatively charged rod touches a neutral electroscope?
If a negatively charged rod touches a neutral electroscope, electrons will flow from the rod to the electroscope, causing the electroscope to become negatively charged. The leaves of the electroscope will repel each other, indicating a charge has been introduced.

What will happen to a negatively charged rod touches a neutral electroscpoe?
When a negatively charged rod touches a neutral electroscope, electrons transfer from the rod to the electroscope, causing the electroscope to become negatively charged. This results in the leaves of the electroscope repelling each other and spreading apart, indicating the presence of an excess negative charge.
How the golden leaf electroscope can be charged postively by induction?
The golden leaf electroscope can be charged positively by induction by first bringing a positively charged object close to the electroscope. The positive charges on the object attract the negative charges in the electroscope, causing the positive charges in the electroscope to be repelled to the leaves, thus giving the electroscope a positive 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.
Is lighting negatively charged or positively charged?
Negatively charge
Are cathodes positively or negatively charged?
Cathodes are negatively charged.
Is an electron positively or negatively charged?
An electron is negatively charged.
