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.
