How to Determine the Charge in a Gold Leaf Electroscope

1. Initial Setup: In a gold leaf electroscope, the gold leaves are initially uncharged and hang close together due to gravity.

2. Charging the Electroscope: When a charged object is brought near the electroscope, it induces a charge on the gold leaves. If the object is negatively charged, electrons in the leaves are repelled, causing them to spread apart.

3. Observing the Gold Leaves: After charging, observe the behavior of the gold leaves. If they diverge further apart, the electroscope is negatively charged. This is because like charges repel each other.

4. Reversing the Charge: To verify the charge, you can bring a positively charged object close to the electroscope. If the gold leaves deflect even more, it indicates that the electroscope was indeed negatively charged.

5. Neutralizing the Charge: To neutralize the charge, you can touch the electroscope with a grounded object, like your hand. This will allow any excess charge to flow to the ground.

6. Final Observation: If the gold leaves come back together after neutralization, it confirms that the initial charge was negative.

By following these steps and careful observations of the gold leaf electroscope, you can accurately determine whether the charge is positive or negative.

Similar Class 12 Doubts

Read the following text and answer the following questions on the basis of the same: Tribo-electric series: The tribo-electric series is a list that ranks materials according to their tendency to gain or lose electrons. The process of electron transfer as a result of two objects coming into contact with one another and then separating is called tribo-electric charging. During such an interaction, one of the two objects will always gain electrons (becoming negatively charge d) and the other object will lose electrons (becoming positively charged). The relative position of the two objects on the tribo-electric series will define which object gains electrons and which object loses electrons.In tribo-electric series, materials are ranked from high to low in terms of the tendency for the material to lose electrons. If an object high up on this list (Glass, for exampl e) is rubbed with an object low down on the list (Teflon, for example), the glass will lose electrons to the teflon. The glass will, in this case, become positively charged and the teflon will become negatively charged. Materials in the middle of the list (steel and wood, for example) are items those do not have a strong tendency to give up or accept electrons.If human hair is rubbed with amber, how those will be charged?
