Why does the gold leaf on an electroscope lift when a charged object is brought near?
The gold leaf on an electroscope lifts when a charged object is brought near because the like charges repel each other. The charged object induces a charge separation in the electroscope, causing the gold leaf to become charged and repel away from the object.
When you charge an electroscope by touching it with a charged balloon the process is called?
The process is called "charging by conduction." When you touch a charged balloon to the electroscope, electrons transfer from the balloon to the electroscope, causing the electroscope to become charged.
How does an electroscope detect charge?
An electroscope detects charge by using a metal rod or leaf that become charged when brought close to a charged object. The charged rod/leaf repels the like charges in the electroscope, causing them to move away from each other. This movement can be visually observed and indicates the presence of a charge.
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.
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 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.
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 does a gold leaf electroscope show that an object is charged?
When a charged object is brought near the metal disc of a gold leaf electroscope, electrons move between the metal disc and the gold leaf, causing the gold leaf to become charged with the same type of charge as the object. This results in the gold leaf repelling from the metal disc, indicating that the object is charged.
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.
If the leaves of an electroscope spread apart it indicates that?
It indicates that the leaves of the electroscope have received a charge.
How come the leaves on a metal leaf electroscope repel?
An electroscope detects the static electrical charge on an object. If an object with a electrical charge is touched to the knob on top this charge is transferred to the rod and in turn to the metal leaves in the jar. Opposite charged objects attract and same charged objects repel. The charge on both leaves is the same polarity so they repel each other.
Would the leaves of an electroscope ever be able to attract to each other?
No, the leaves of an electroscope will not attract to each other. When the leaves of an electroscope become charged due to an electric field or charge presence, they will repel each other due to like charges. Attraction between the leaves is not possible in this scenario.
